31950107 ÷ 831 
We want to divide 31950107 by 831.

Moving on to step 1:
3 divided by 831 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 831

Going ahead to step 2:
831 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 831

Moving on to step 3:
The number 831 fits into 319 0 times, leaving a remainder of 319.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 319 after subtracting 0 from 319.
Append the next digit (5) from the dividend to 319 and continue with: 3195 / 831

Moving on to step 4:
3195 divided by 831 is 3 with a remainder of 702.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2493 from 3195, we get 702.
Take the next digit (0) from the dividend and append it to 702, then repeat: 7020 / 831

Step 5:
831 can be fit into 7020 8 times, resulting in a remainder of 372.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Deduct 6648 from 7020 and we're left with 372.
Take the next digit (1) from the dividend and append it to 372, then repeat: 3721 / 831

On to step 6:
831 goes into 3721 4 times with a remainder of 397.
Record the quotient 4 as the next digit in the result. 
Result so far: 384.0
Subtracting 3324 from 3721 leaves us with 397.
Grab the next digit (0) from the dividend, add it to 397, then carry on: 3970 / 831

On to step 7:
3970 divided by 831 is 4 with a remainder of 646.
The number 4 becomes the next digit in our result. 
Result so far: 3844.0
Subtracting 3324 from 3970 leaves us with 646.
Take the next digit (7) from the dividend and append it to 646, then repeat: 6467 / 831

Going ahead to step 8:
The number 831 fits into 6467 7 times, leaving a remainder of 650.
The number 7 becomes the next digit in our result. 
Result so far: 38447.0
If we subtract 5817 from 6467, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 9:
6500 divided by 831 is 7 with a remainder of 683.
The number 7 becomes the next digit in our result. 
Result so far: 38447.7
If we subtract 5817 from 6500, we get 683.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6830, and continue the process.

Let's proceed to step 10:
If we divide 6830 by 831, we get 8 and a remainder of 182.
Write down 8 as next digit of the result. 
Result so far: 38447.78
The remainder is 182 after subtracting 6648 from 6830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 11:
The number 831 fits into 1820 2 times, leaving a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 38447.782
If we subtract 1662 from 1820, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 12:
831 goes into 1580 1 times with a remainder of 749.
Use 1 as the next digit of our solution. 
Result so far: 38447.7821
If we subtract 831 from 1580, we get 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

Moving on to step 13:
7490 divided by 831 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 38447.78219
If we subtract 7479 from 7490, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
831 goes into 110 0 times with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 38447.78219
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 15:
1100 divided by 831 is 1 with a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 38447.7821901
Subtracting 831 from 1100 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 16:
831 can be fit into 2690 3 times, resulting in a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 38447.78219013
Subtracting 2493 from 2690 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The final result is 38447.78219013 with a remainder of 1.97e-07.
