Let's divide 917639 by 99
We want to figure out the number of times 917639 can be divided by 99.

Going ahead to step 1:
9 divided by 99 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 99

Step 2:
When dividing 91 by 99, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Fetch the next digit (7) from the dividend, attach it to 91 and continue: 917 / 99

Moving on to step 3:
917 divided by 99 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 891 from 917 to get 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 99

On to step 4:
99 goes into 266 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
The remainder is 68 after subtracting 198 from 266.
Bring next digit (3) of the dividend behind the 68 and repeat the process: 683 / 99

On to step 5:
99 goes into 683 6 times with a remainder of 89.
Record the quotient 6 as the next digit in the result. 
Result so far: 926.0
The remainder is 89 after subtracting 594 from 683.
Grab the next digit (9) from the dividend, add it to 89, then carry on: 899 / 99

On to step 6:
899 divided by 99 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 9269.0
If we take 891 away from 899, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
99 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 9269.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
The number 99 fits into 800 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 9269.08
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
99 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 9269.08
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
When dividing 800 by 99, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 9269.0808
If we take 792 away from 800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 99, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 9269.0808
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
If we divide 800 by 99, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 9269.080808
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
When dividing 80 by 99, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 9269.080808
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
800 divided by 99 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 9269.08080808
If we subtract 792 from 800, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 9269.08080808, and the remainder is 8e-09.
