Let's divide 86288881 by 99
Our goal is to divide 86288881 by 99.

Moving on to step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
Write down 0 as next digit of 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:
If we divide 86 by 99, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (2) of the dividend behind the 86 and repeat the process: 862 / 99

Step 3:
When dividing 862 by 99, we get 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 792 from 862 to get 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 99

Advancing to step 4:
99 can be fit into 708 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 87.0
Subtracting 693 from 708 leaves us with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 99

Let's proceed to step 5:
99 goes into 158 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 871.0
The remainder is 59 after subtracting 99 from 158.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 99

Let's proceed to step 6:
99 goes into 598 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 8716.0
Deduct 594 from 598 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 99

Let's proceed to step 7:
If we divide 48 by 99, we get 0 and a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 87160.0
If we take 0 away from 48, we end up with 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 99

Going ahead to step 8:
481 divided by 99 is 4 with a remainder of 85.
Put 4 as the next digit of the answer. 
Result so far: 871604.0
Subtract 396 from 481 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 9:
If we divide 850 by 99, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 871604.8
The remainder is 58 after subtracting 792 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
99 goes into 580 5 times with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 871604.85
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
850 divided by 99 is 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 871604.858
If we subtract 792 from 850, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
The number 99 fits into 580 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 871604.8585
The remainder is 85 after subtracting 495 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 13:
850 divided by 99 is 8 with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 871604.85858
The remainder is 58 after subtracting 792 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
99 goes into 580 5 times with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 871604.858585
Deduct 495 from 580 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 15:
If we divide 850 by 99, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 871604.8585858
Subtracting 792 from 850 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
99 goes into 580 5 times with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 871604.85858585
If we take 495 away from 580, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The quotient of the division is 871604.85858585, and the remainder is 8.5e-08.
