Let's divide 81192422 by 831
We want to divide 81192422 by 831.

On to step 1:
When dividing 8 by 831, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 831

Step 2:
81 divided by 831 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 831

Advancing to step 3:
The number 831 fits into 811 0 times, leaving a remainder of 811.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 811, we get 811.
Fetch the next digit (9) from the dividend, attach it to 811 and continue: 8119 / 831

Going ahead to step 4:
If we divide 8119 by 831, we get 9 and a remainder of 640.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7479 from 8119 leaves us with 640.
Take the next digit (2) from the dividend and append it to 640, then repeat: 6402 / 831

Advancing to step 5:
831 can be fit into 6402 7 times, resulting in a remainder of 585.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
The remainder is 585 after subtracting 5817 from 6402.
Bring next digit (4) of the dividend behind the 585 and repeat the process: 5854 / 831

Step 6:
831 goes into 5854 7 times with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 977.0
Subtract 5817 from 5854 to get 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 831

Let's proceed to step 7:
The number 831 fits into 372 0 times, leaving a remainder of 372.
Put 0 as the next digit of the answer. 
Result so far: 9770.0
Subtracting 0 from 372 leaves us with 372.
Append the next digit (2) from the dividend to 372 and continue with: 3722 / 831

Let's proceed to step 8:
831 can be fit into 3722 4 times, resulting in a remainder of 398.
Write down 4 as next digit of the result. 
Result so far: 97704.0
Subtract 3324 from 3722 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 9:
The number 831 fits into 3980 4 times, leaving a remainder of 656.
Write down 4 as next digit of the result. 
Result so far: 97704.4
Subtracting 3324 from 3980 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 10:
The number 831 fits into 6560 7 times, leaving a remainder of 743.
The next digit of our result is 7. 
Result so far: 97704.47
Subtracting 5817 from 6560 leaves us with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Advancing to step 11:
7430 divided by 831 is 8 with a remainder of 782.
Use 8 as the next digit of our solution. 
Result so far: 97704.478
If we take 6648 away from 7430, we end up with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Going ahead to step 12:
831 can be fit into 7820 9 times, resulting in a remainder of 341.
Use 9 as the next digit of our solution. 
Result so far: 97704.4789
If we take 7479 away from 7820, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 13:
831 goes into 3410 4 times with a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 97704.47894
If we take 3324 away from 3410, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 14:
When dividing 860 by 831, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 97704.478941
If we take 831 away from 860, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 15:
The number 831 fits into 290 0 times, leaving a remainder of 290.
The next digit of our result is 0. 
Result so far: 97704.478941
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 16:
2900 divided by 831 is 3 with a remainder of 407.
Write down 3 as next digit of the result. 
Result so far: 97704.47894103
If we take 2493 away from 2900, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

The final result is 97704.47894103 with a remainder of 4.07e-07.
