We divide 388826 by 31
Our goal is to divide 388826 by 31.

On to step 1:
3 divided by 31 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 31

Going ahead to step 2:
If we divide 38 by 31, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 31 from 38, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 31

On to step 3:
78 divided by 31 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 12.0
If we take 62 away from 78, we end up with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 31

Going ahead to step 4:
31 can be fit into 168 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
The remainder is 13 after subtracting 155 from 168.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 31

Step 5:
If we divide 132 by 31, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1254.0
If we take 124 away from 132, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 31

Let's proceed to step 6:
31 can be fit into 86 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 12542.0
If we subtract 62 from 86, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
If we divide 240 by 31, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 12542.7
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 12542.77
Subtracting 217 from 230 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 12542.77 with a remaining 0.013.
