Let's divide 81959107 by 921
We want to figure out the number of times 81959107 can be divided by 921.

Step 1:
If we divide 8 by 921, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 921

Let's proceed to step 2:
If we divide 81 by 921, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 921

Advancing to step 3:
The number 921 fits into 819 0 times, leaving a remainder of 819.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 819, we get 819.
Append the next digit (5) from the dividend to 819 and continue with: 8195 / 921

Moving on to step 4:
921 can be fit into 8195 8 times, resulting in a remainder of 827.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7368 from 8195 to get 827.
Grab the next digit (9) from the dividend, add it to 827, then carry on: 8279 / 921

Going ahead to step 5:
8279 divided by 921 is 8 with a remainder of 911.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Deduct 7368 from 8279 and we're left with 911.
Grab the next digit (1) from the dividend, add it to 911, then carry on: 9111 / 921

On to step 6:
9111 divided by 921 is 9 with a remainder of 822.
Write down 9 as next digit of the result. 
Result so far: 889.0
Subtract 8289 from 9111 to get 822.
Include the next digit (0) from the dividend after 822, then repeat: 8220 / 921

Step 7:
921 can be fit into 8220 8 times, resulting in a remainder of 852.
Write down 8 as next digit of the result. 
Result so far: 8898.0
Subtracting 7368 from 8220 leaves us with 852.
Grab the next digit (7) from the dividend, add it to 852, then carry on: 8527 / 921

On to step 8:
921 can be fit into 8527 9 times, resulting in a remainder of 238.
Put 9 as the next digit of the answer. 
Result so far: 88989.0
Deduct 8289 from 8527 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 9:
When dividing 2380 by 921, we get 2 with a remainder of 538.
The next digit of our result is 2. 
Result so far: 88989.2
If we subtract 1842 from 2380, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 10:
921 can be fit into 5380 5 times, resulting in a remainder of 775.
Record the quotient 5 as the next digit in the result. 
Result so far: 88989.25
If we take 4605 away from 5380, we end up with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Let's proceed to step 11:
921 goes into 7750 8 times with a remainder of 382.
The next digit of our result is 8. 
Result so far: 88989.258
If we take 7368 away from 7750, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 12:
If we divide 3820 by 921, we get 4 and a remainder of 136.
The next digit of our result is 4. 
Result so far: 88989.2584
Deduct 3684 from 3820 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 13:
When dividing 1360 by 921, we get 1 with a remainder of 439.
Put 1 as the next digit of the answer. 
Result so far: 88989.25841
If we take 921 away from 1360, we end up with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 14:
4390 divided by 921 is 4 with a remainder of 706.
Put 4 as the next digit of the answer. 
Result so far: 88989.258414
Deduct 3684 from 4390 and we're left with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Step 15:
921 can be fit into 7060 7 times, resulting in a remainder of 613.
Use 7 as the next digit of our solution. 
Result so far: 88989.2584147
Subtracting 6447 from 7060 leaves us with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

On to step 16:
6130 divided by 921 is 6 with a remainder of 604.
Use 6 as the next digit of our solution. 
Result so far: 88989.25841476
If we take 5526 away from 6130, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

The quotient of the division is 88989.25841476, and the remainder is 6.04e-07.
