Solution
Your input: convert 390042 into a decimal.
Write the problem in the special format:
−92.857142857142842−3900
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⋅42=3−0=3.
Bring down the next digit of the dividend.
−0092.857142857142842−39↓00.0000000000000−9000.000000000000lll0.lll39.
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⋅42=39−0=39.
Bring down the next digit of the dividend.
−0092.857142857142842−390↓0.0000000000000−9000.000000000000lll0.lll39.−9000.000000000000lll0.lll390.
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⋅42=390−378=12.
Bring down the next digit of the dividend.
−0092.857142857142842−3900↓.0000000000000−9000.000000000000lll0.lll39.−9000.000000000000lll0.lll390.−9000.000000000000lll378.lll120.
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⋅42=120−84=36.
Bring down the next digit of the dividend.
−0092.857142857142842−3900.0↓000000000000−9000.000000000000lll0.lll39.−9000.000000000000lll0.lll390.−9000.000000000000lll378.lll120.−900.0000000000000lll84.lll36.0
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⋅42=360−336=24.
Bring down the next digit of the dividend.
−0092.857142857142842−3900.00↓00000000000−9000.000000000000lll0.lll39.−9000.000000000000lll0.lll390.−9000.000000000000lll378.lll120.−900.0000000000000lll84.lll36.0−00.0000000000000lll33.6lll2.40
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⋅42=240−210=30.
Bring down the next digit of the dividend.
−0092.857142857142842−3900.000↓0000000000−9000.000000000000lll0.lll39.−9000.000000000000lll0.lll390.−9000.000000000000lll378.lll120.−900.0000000000000lll84.lll36.0−00.0000000000000lll33.6lll2.40−0.0000000000000lll2.10lll300
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.

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}
