Fraction to Decimal Calculator

Convert fractions to decimals step by step

The calculator will convert the given fraction (proper or improper) or mixed number into a decimal (possibly, repeating or recurring), with steps shown.

Enter a fraction or

If you don't need a mixed number, leave the left cell empty.
If you need a negative fraction, write the minus sign in the left cell.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Solution

Your input: convert 12300200 into a decimal.

Write the problem in the special format:

\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{ccccc}\phantom{6}&\phantom{1}&\phantom{.}&\phantom{5}\end{array}&\\200&\phantom{-}\enclose{longdiv}{\begin{array}{ccccc}1&2&3&0&0\end{array}}&\\&\begin{array}{lllll}\end{array}&\begin{array}{c}\end{array}\end{array}

Step 1

How many 200's are in 1? The answer is 0.

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

Now, 1-0 \cdot 200 = 1 - 0= 1.

Bring down the next digit of the dividend.

\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{ccccccc}\color{DarkCyan}{0}&\phantom{0}&\phantom{0}&\phantom{6}&\phantom{1}&\phantom{.}&\phantom{5}\end{array}&\\\color{Magenta}{200}&\phantom{-}\enclose{longdiv}{\begin{array}{ccccccc}\color{DarkCyan}{1}& 2 \downarrow&3&0&0&.&0\end{array}}&\\&\begin{array}{llllll}-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}1&2&\phantom{.}\end{array}&\begin{array}{c}\end{array}\end{array}

Step 2

How many 200's are in 12? The answer is 0.

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

Now, 12-0 \cdot 200 = 12 - 0= 12.

Bring down the next digit of the dividend.

\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{ccccccc}0&\color{Purple}{0}&\phantom{0}&\phantom{6}&\phantom{1}&\phantom{.}&\phantom{5}\end{array}&\\\color{Magenta}{200}&\phantom{-}\enclose{longdiv}{\begin{array}{ccccccc}1&2& 3 \downarrow&0&0&.&0\end{array}}&\\&\begin{array}{llllll}-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}\color{Purple}{1}&\color{Purple}{2}&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&0&\phantom{.}\\\hline\phantom{lll}1&2&3&\phantom{.}\end{array}&\begin{array}{c}\end{array}\end{array}

Step 3

How many 200's are in 123? The answer is 0.

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

Now, 123-0 \cdot 200 = 123 - 0= 123.

Bring down the next digit of the dividend.

\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{ccccccc}0&0&\color{Chartreuse}{0}&\phantom{6}&\phantom{1}&\phantom{.}&\phantom{5}\end{array}&\\\color{Magenta}{200}&\phantom{-}\enclose{longdiv}{\begin{array}{ccccccc}1&2&3& 0 \downarrow&0&.&0\end{array}}&\\&\begin{array}{llllll}-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}1&2&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&0&\phantom{.}\\\hline\phantom{lll}\color{Chartreuse}{1}&\color{Chartreuse}{2}&\color{Chartreuse}{3}&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&&0&\phantom{.}\\\hline\phantom{lll}1&2&3&0&\phantom{.}\end{array}&\begin{array}{c}\end{array}\end{array}

Step 4

How many 200's are in 1230? The answer is 6.

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

Now, 1230-6 \cdot 200 = 1230 - 1200= 30.

Bring down the next digit of the dividend.

\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{ccccccc}0&0&0&\color{OrangeRed}{6}&\phantom{1}&\phantom{.}&\phantom{5}\end{array}&\\\color{Magenta}{200}&\phantom{-}\enclose{longdiv}{\begin{array}{ccccccc}1&2&3&0& 0 \downarrow&.&0\end{array}}&\\&\begin{array}{llllll}-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}1&2&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&0&\phantom{.}\\\hline\phantom{lll}1&2&3&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&&0&\phantom{.}\\\hline\phantom{lll}\color{OrangeRed}{1}&\color{OrangeRed}{2}&\color{OrangeRed}{3}&\color{OrangeRed}{0}&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}1&2&0&0&\phantom{.}\\\hline\phantom{lll}&&3&0&0&\phantom{.}\end{array}&\begin{array}{c}\end{array}\end{array}

Step 5

How many 200's are in 300? The answer is 1.

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

Now, 300-1 \cdot 200 = 300 - 200= 100.

Bring down the next digit of the dividend.

\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{ccccccc}0&0&0&6&\color{DarkBlue}{1}&\phantom{.}&\phantom{5}\end{array}&\\\color{Magenta}{200}&\phantom{-}\enclose{longdiv}{\begin{array}{ccccccc}1&2&3&0&0&.& 0 \downarrow\end{array}}&\\&\begin{array}{llllll}-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}1&2&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&0&\phantom{.}\\\hline\phantom{lll}1&2&3&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&&0&\phantom{.}\\\hline\phantom{lll}1&2&3&0&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}1&2&0&0&\phantom{.}\\\hline\phantom{lll}&&\color{DarkBlue}{3}&\color{DarkBlue}{0}&\color{DarkBlue}{0}&\phantom{.}\\&-&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}\\\phantom{lll}&&2&0&0&\phantom{.}\\\hline\phantom{lll}&&1&0&0&\phantom{.}&0\end{array}&\begin{array}{c}\end{array}\end{array}

Step 6

How many 200's are in 1000? The answer is 5.

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

Now, 1000-5 \cdot 200 = 1000 - 1000= 0.

\require{enclose}\begin{array}{rlc}&\phantom{-\enclose{longdiv}{}}\begin{array}{ccccccc}0&0&0&6&1&.&\color{Chocolate}{5}\end{array}&\\\color{Magenta}{200}&\phantom{-}\enclose{longdiv}{\begin{array}{ccccccc}1&2&3&0&0&.&0\end{array}}&\\&\begin{array}{llllll}-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}0&\phantom{.}\\\hline\phantom{lll}1&2&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&0&\phantom{.}\\\hline\phantom{lll}1&2&3&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}&&0&\phantom{.}\\\hline\phantom{lll}1&2&3&0&\phantom{.}\\-&\phantom{2}&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{0}&\phantom{.}\\\phantom{lll}1&2&0&0&\phantom{.}\\\hline\phantom{lll}&&3&0&0&\phantom{.}\\&-&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}\\\phantom{lll}&&2&0&0&\phantom{.}\\\hline\phantom{lll}&&\color{Chocolate}{1}&\color{Chocolate}{0}&\color{Chocolate}{0}&\phantom{.}&\color{Chocolate}{0}\\&-&\phantom{3}&\phantom{0}&\phantom{0}&\phantom{.}&\phantom{0}\\\phantom{lll}&&1&0&0&\phantom{.}&0\\\hline\phantom{lll}&&&&&&0\end{array}&\begin{array}{c}\end{array}\end{array}

Since the remainder is 0, then we are done.

Therefore, \frac{12300}{200}=61.5

Answer: \frac{12300}{200}=61.5
