We look at the division of 866884 by 99 
Let's see how many times 99 fits into 866884.

Step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 99

Going ahead to step 2:
When dividing 86 by 99, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 99

Moving on to step 3:
99 goes into 866 8 times with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 74 after subtracting 792 from 866.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 99

Going ahead to step 4:
99 can be fit into 748 7 times, resulting in a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
The remainder is 55 after subtracting 693 from 748.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 99

Advancing to step 5:
The number 99 fits into 558 5 times, leaving a remainder of 63.
The number 5 becomes the next digit in our result. 
Result so far: 875.0
If we subtract 495 from 558, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 99

Going ahead to step 6:
When dividing 634 by 99, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 8756.0
If we subtract 594 from 634, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
99 can be fit into 400 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 8756.4
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 99 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8756.4
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 99, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 8756.404
Subtract 396 from 400 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 99 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8756.404
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 99, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 8756.40404
If we take 396 away from 400, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
If we divide 40 by 99, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 8756.40404
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
The number 99 fits into 400 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 8756.4040404
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
40 divided by 99 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8756.4040404
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 8756.4040404 with a remaining 4e-08.
