Let's divide 857091 by 99
We want to figure out the number of times 857091 can be divided by 99.

On to step 1:
8 divided by 99 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 99

Going ahead to step 2:
85 divided by 99 is 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Fetch the next digit (7) from the dividend, attach it to 85 and continue: 857 / 99

Let's proceed to step 3:
The number 99 fits into 857 8 times, leaving a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 792 from 857, we get 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 99

Let's proceed to step 4:
650 divided by 99 is 6 with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 594 from 650 leaves us with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 99

Step 5:
The number 99 fits into 569 5 times, leaving a remainder of 74.
Use 5 as the next digit of our solution. 
Result so far: 865.0
Subtracting 495 from 569 leaves us with 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 99

Let's proceed to step 6:
The number 99 fits into 741 7 times, leaving a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 8657.0
If we subtract 693 from 741, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
When dividing 480 by 99, we get 4 with a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 8657.4
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 8:
840 divided by 99 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 8657.48
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
99 goes into 480 4 times with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 8657.484
The remainder is 84 after subtracting 396 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
99 goes into 840 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 8657.4848
The remainder is 48 after subtracting 792 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
99 can be fit into 480 4 times, resulting in a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 8657.48484
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
99 can be fit into 840 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 8657.484848
The remainder is 48 after subtracting 792 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
The number 99 fits into 480 4 times, leaving a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 8657.4848484
If we subtract 396 from 480, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
If we divide 840 by 99, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 8657.48484848
Subtract 792 from 840 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 8657.48484848, and the remainder is 4.8e-08.
