We're dividing 864160 by 99 
We're looking to find how many times 99 goes into 864160.

On to step 1:
99 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 99

Going ahead to step 2:
99 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 99

Going ahead to step 3:
When dividing 864 by 99, we get 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 72 after subtracting 792 from 864.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 99

Going ahead to step 4:
When dividing 721 by 99, we get 7 with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 693 away from 721, we end up with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 99

On to step 5:
The number 99 fits into 286 2 times, leaving a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
Subtract 198 from 286 to get 88.
Fetch the next digit (0) from the dividend, attach it to 88 and continue: 880 / 99

Moving on to step 6:
The number 99 fits into 880 8 times, leaving a remainder of 88.
The next digit of our result is 8. 
Result so far: 8728.0
The remainder is 88 after subtracting 792 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 7:
The number 99 fits into 880 8 times, leaving a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 8728.8
Subtract 792 from 880 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 8:
99 can be fit into 880 8 times, resulting in a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 8728.88
The remainder is 88 after subtracting 792 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 8728.88, and the remainder is 0.088.
