Calcolatrice da frazione a decimale

Your input: convert $\frac{3900}{42}$ into a decimal.

Write the problem in the special format:

$\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{cccc}\phantom{9}&\phantom{2}&\phantom{.}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}\end{array}&\\42&\phantom{-}\enclose{longdiv}{\begin{array}{cccc}3&9&0&0\end{array}}&\\&\begin{array}{llll}\end{array}&\begin{array}{c}\end{array}\end{array}$

Step 1

How many $42$'s are in $3$? The answer is $0$.

Write down the calculated result in the upper part of the table.

Now, $3-0 \cdot 42 = 3 - 0= 3$.

Bring down the next digit of the dividend.

$\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{cccccccccccccccccc}\color{DarkBlue}{0}&\phantom{0}&\phantom{9}&\phantom{2}&\phantom{.}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}\end{array}&\\\color{Magenta}{42}&\phantom{-}\enclose{longdiv}{\begin{array}{cccccccccccccccccc}\color{DarkBlue}{3}& 9 \downarrow&0&0&.&0&0&0&0&0&0&0&0&0&0&0&0&0\end{array}}&\\&\begin{array}{lllllllllllllllll}-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}3&9&\phantom{.}\end{array}&\begin{array}{c}\end{array}\end{array}$

Step 2

How many $42$'s are in $39$? The answer is $0$.

Write down the calculated result in the upper part of the table.

Now, $39-0 \cdot 42 = 39 - 0= 39$.

Bring down the next digit of the dividend.

$\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{cccccccccccccccccc}0&\color{Chocolate}{0}&\phantom{9}&\phantom{2}&\phantom{.}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}\end{array}&\\\color{Magenta}{42}&\phantom{-}\enclose{longdiv}{\begin{array}{cccccccccccccccccc}3&9& 0 \downarrow&0&.&0&0&0&0&0&0&0&0&0&0&0&0&0\end{array}}&\\&\begin{array}{lllllllllllllllll}-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}\color{Chocolate}{3}&\color{Chocolate}{9}&\phantom{.}\\-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}&0&\phantom{.}\\\hline\phantom{lll}3&9&0&\phantom{.}\end{array}&\begin{array}{c}\end{array}\end{array}$

Step 3

How many $42$'s are in $390$? The answer is $9$.

Write down the calculated result in the upper part of the table.

Now, $390-9 \cdot 42 = 390 - 378= 12$.

Bring down the next digit of the dividend.

$\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{cccccccccccccccccc}0&0&\color{Brown}{9}&\phantom{2}&\phantom{.}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}\end{array}&\\\color{Magenta}{42}&\phantom{-}\enclose{longdiv}{\begin{array}{cccccccccccccccccc}3&9&0& 0 \downarrow&.&0&0&0&0&0&0&0&0&0&0&0&0&0\end{array}}&\\&\begin{array}{lllllllllllllllll}-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}3&9&\phantom{.}\\-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}&0&\phantom{.}\\\hline\phantom{lll}\color{Brown}{3}&\color{Brown}{9}&\color{Brown}{0}&\phantom{.}\\-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}3&7&8&\phantom{.}\\\hline\phantom{lll}&1&2&0&\phantom{.}\end{array}&\begin{array}{c}\end{array}\end{array}$

Step 4

How many $42$'s are in $120$? The answer is $2$.

Write down the calculated result in the upper part of the table.

Now, $120-2 \cdot 42 = 120 - 84= 36$.

Bring down the next digit of the dividend.

Step 5

How many $42$'s are in $360$? The answer is $8$.

Write down the calculated result in the upper part of the table.

Now, $360-8 \cdot 42 = 360 - 336= 24$.

Bring down the next digit of the dividend.

$\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{cccccccccccccccccc}0&0&9&2&.&\color{Violet}{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}&\phantom{5}&\phantom{7}&\phantom{1}&\phantom{4}&\phantom{2}&\phantom{8}\end{array}&\\\color{Magenta}{42}&\phantom{-}\enclose{longdiv}{\begin{array}{cccccccccccccccccc}3&9&0&0&.&0& 0 \downarrow&0&0&0&0&0&0&0&0&0&0&0\end{array}}&\\&\begin{array}{lllllllllllllllll}-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}3&9&\phantom{.}\\-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}&0&\phantom{.}\\\hline\phantom{lll}3&9&0&\phantom{.}\\-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}3&7&8&\phantom{.}\\\hline\phantom{lll}&1&2&0&\phantom{.}\\-&\phantom{9}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}&&8&4&\phantom{.}\\\hline\phantom{lll}&&\color{Violet}{3}&\color{Violet}{6}&\phantom{.}&\color{Violet}{0}\\&-&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{0}\\\phantom{lll}&&3&3&\phantom{.}&6\\\hline\phantom{lll}&&&2&\phantom{.}&4&0\end{array}&\begin{array}{c}\end{array}\end{array}$

Step 6

How many $42$'s are in $240$? The answer is $5$.

Write down the calculated result in the upper part of the table.

Now, $240-5 \cdot 42 = 240 - 210= 30$.

Bring down the next digit of the dividend.

Step 7

How many $42$'s are in $300$? The answer is $7$.

Write down the calculated result in the upper part of the table.

Now, $300-7 \cdot 42 = 300 - 294= 6$.

Bring down the next digit of the dividend.

Write down the calculated result in the upper part of the table.

Now, $60-1 \cdot 42 = 60 - 42= 18$.

Bring down the next digit of the dividend.

Step 10

How many $42$'s are in $120$? The answer is $2$.

Write down the calculated result in the upper part of the table.

Step 11

How many $42$'s are in $360$? The answer is $8$.

Write down the calculated result in the upper part of the table.

Step 12

How many $42$'s are in $240$? The answer is $5$.

Write down the calculated result in the upper part of the table.

Now, $240-5 \cdot 42 = 240 - 210= 30$.

Step 16

How many $42$'s are in $120$? The answer is $2$.

Write down the calculated result in the upper part of the table.

Now, $120-2 \cdot 42 = 120 - 84= 36$.

How many $42$'s are in $360$? The answer is $8$.

Write down the calculated result in the upper part of the table.

Now, $360-8 \cdot 42 = 360 - 336= 24$.

As can be seen, the digits are repeating with some period, therefore it is a repeating (or recurring) decimal: $\frac{3900}{42}=92.8 \overline{571428}$

Answer: $\frac{3900}{42}=92.8\overline{571428}$
