Let's divide 81931131 by 822
We want to divide 81931131 by 822.

Let's proceed to step 1:
If we divide 8 by 822, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 822

Going ahead to step 2:
The number 822 fits into 81 0 times, leaving a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 822

Step 3:
When dividing 819 by 822, we get 0 with a remainder of 819.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 819 to get 819.
Grab the next digit (3) from the dividend, add it to 819, then carry on: 8193 / 822

Going ahead to step 4:
When dividing 8193 by 822, we get 9 with a remainder of 795.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 795 after subtracting 7398 from 8193.
Append the next digit (1) from the dividend to 795 and continue with: 7951 / 822

Advancing to step 5:
If we divide 7951 by 822, we get 9 and a remainder of 553.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 7398 from 7951, we get 553.
Fetch the next digit (1) from the dividend, attach it to 553 and continue: 5531 / 822

On to step 6:
The number 822 fits into 5531 6 times, leaving a remainder of 599.
The next digit of our result is 6. 
Result so far: 996.0
If we subtract 4932 from 5531, we get 599.
Fetch the next digit (3) from the dividend, attach it to 599 and continue: 5993 / 822

Going ahead to step 7:
822 goes into 5993 7 times with a remainder of 239.
Put 7 as the next digit of the answer. 
Result so far: 9967.0
Deduct 5754 from 5993 and we're left with 239.
Fetch the next digit (1) from the dividend, attach it to 239 and continue: 2391 / 822

Step 8:
2391 divided by 822 is 2 with a remainder of 747.
Write down 2 as next digit of the result. 
Result so far: 99672.0
Subtracting 1644 from 2391 leaves us with 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Moving on to step 9:
7470 divided by 822 is 9 with a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 99672.9
If we take 7398 away from 7470, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
The number 822 fits into 720 0 times, leaving a remainder of 720.
Record the quotient 0 as the next digit in the result. 
Result so far: 99672.9
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 11:
The number 822 fits into 7200 8 times, leaving a remainder of 624.
Record the quotient 8 as the next digit in the result. 
Result so far: 99672.908
The remainder is 624 after subtracting 6576 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 12:
6240 divided by 822 is 7 with a remainder of 486.
The number 7 becomes the next digit in our result. 
Result so far: 99672.9087
If we subtract 5754 from 6240, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 13:
822 goes into 4860 5 times with a remainder of 750.
The number 5 becomes the next digit in our result. 
Result so far: 99672.90875
The remainder is 750 after subtracting 4110 from 4860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 14:
822 can be fit into 7500 9 times, resulting in a remainder of 102.
Write down 9 as next digit of the result. 
Result so far: 99672.908759
Subtracting 7398 from 7500 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 15:
The number 822 fits into 1020 1 times, leaving a remainder of 198.
Use 1 as the next digit of our solution. 
Result so far: 99672.9087591
Deduct 822 from 1020 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 16:
If we divide 1980 by 822, we get 2 and a remainder of 336.
The next digit of our result is 2. 
Result so far: 99672.90875912
If we take 1644 away from 1980, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

In conclusion, the division gives 99672.90875912 with a balance of 3.36e-07.
