Let's divide 87749232 by 869
We want to figure out the number of times 87749232 can be divided by 869.

Going ahead to step 1:
If we divide 8 by 869, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 869

On to step 2:
When dividing 87 by 869, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 869

On to step 3:
If we divide 877 by 869, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 869 from 877 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 869

Moving on to step 4:
When dividing 84 by 869, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 84 after subtracting 0 from 84.
Fetch the next digit (9) from the dividend, attach it to 84 and continue: 849 / 869

Advancing to step 5:
869 can be fit into 849 0 times, resulting in a remainder of 849.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 849, we get 849.
Take the next digit (2) from the dividend and append it to 849, then repeat: 8492 / 869

Advancing to step 6:
8492 divided by 869 is 9 with a remainder of 671.
The number 9 becomes the next digit in our result. 
Result so far: 1009.0
Deduct 7821 from 8492 and we're left with 671.
Include the next digit (3) from the dividend after 671, then repeat: 6713 / 869

Advancing to step 7:
If we divide 6713 by 869, we get 7 and a remainder of 630.
Use 7 as the next digit of our solution. 
Result so far: 10097.0
If we take 6083 away from 6713, we end up with 630.
Append the next digit (2) from the dividend to 630 and continue with: 6302 / 869

Step 8:
869 goes into 6302 7 times with a remainder of 219.
Put 7 as the next digit of the answer. 
Result so far: 100977.0
Subtracting 6083 from 6302 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 9:
When dividing 2190 by 869, we get 2 with a remainder of 452.
The next digit of our result is 2. 
Result so far: 100977.2
Subtracting 1738 from 2190 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 10:
869 can be fit into 4520 5 times, resulting in a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 100977.25
If we subtract 4345 from 4520, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 11:
The number 869 fits into 1750 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 100977.252
The remainder is 12 after subtracting 1738 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
869 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 100977.252
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
869 can be fit into 1200 1 times, resulting in a remainder of 331.
Write down 1 as next digit of the result. 
Result so far: 100977.25201
The remainder is 331 after subtracting 869 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 14:
When dividing 3310 by 869, we get 3 with a remainder of 703.
Record the quotient 3 as the next digit in the result. 
Result so far: 100977.252013
If we take 2607 away from 3310, we end up with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Moving on to step 15:
869 can be fit into 7030 8 times, resulting in a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 100977.2520138
If we subtract 6952 from 7030, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 16:
869 can be fit into 780 0 times, resulting in a remainder of 780.
The next digit of our result is 0. 
Result so far: 100977.2520138
If we subtract 0 from 780, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

The final result is 100977.2520138 with a remainder of 7.8e-07.
