Let's divide 31855901 by 109
We want to divide 31855901 by 109.

Advancing to step 1:
The number 109 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 109

On to step 2:
109 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 109

Moving on to step 3:
318 divided by 109 is 2 with a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 218 from 318, we get 100.
Bring next digit (5) of the dividend behind the 100 and repeat the process: 1005 / 109

Advancing to step 4:
109 can be fit into 1005 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 981 from 1005 to get 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 109

On to step 5:
109 goes into 245 2 times with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 292.0
Subtracting 218 from 245 leaves us with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 109

Going ahead to step 6:
279 divided by 109 is 2 with a remainder of 61.
The next digit of our result is 2. 
Result so far: 2922.0
If we subtract 218 from 279, we get 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 109

Moving on to step 7:
109 goes into 610 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 29225.0
If we subtract 545 from 610, we get 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 109

Step 8:
109 goes into 651 5 times with a remainder of 106.
The next digit of our result is 5. 
Result so far: 292255.0
If we take 545 away from 651, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 9:
When dividing 1060 by 109, we get 9 with a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 292255.9
Subtracting 981 from 1060 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 10:
The number 109 fits into 790 7 times, leaving a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 292255.97
Deduct 763 from 790 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
When dividing 270 by 109, we get 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 292255.972
If we subtract 218 from 270, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
When dividing 520 by 109, we get 4 with a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 292255.9724
If we take 436 away from 520, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 13:
109 can be fit into 840 7 times, resulting in a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 292255.97247
Subtract 763 from 840 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 14:
109 goes into 770 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 292255.972477
Subtract 763 from 770 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 292255.972477, with a leftover of 7e-07.
