Let's divide 891861 by 99
We're looking to find how many times 99 goes into 891861.

Going ahead to step 1:
8 divided by 99 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 99

Going ahead to step 2:
89 divided by 99 is 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Grab the next digit (1) from the dividend, add it to 89, then carry on: 891 / 99

Let's proceed to step 3:
99 can be fit into 891 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 891 from 891 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 99

Step 4:
99 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 99

Advancing to step 5:
99 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 900.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (1) from the dividend after 86, then repeat: 861 / 99

Advancing to step 6:
The number 99 fits into 861 8 times, leaving a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 9008.0
Subtract 792 from 861 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
The number 99 fits into 690 6 times, leaving a remainder of 96.
The next digit of our result is 6. 
Result so far: 9008.6
The remainder is 96 after subtracting 594 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 8:
When dividing 960 by 99, we get 9 with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 9008.69
The remainder is 69 after subtracting 891 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
99 can be fit into 690 6 times, resulting in a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 9008.696
If we take 594 away from 690, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 10:
The number 99 fits into 960 9 times, leaving a remainder of 69.
The next digit of our result is 9. 
Result so far: 9008.6969
Subtract 891 from 960 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 11:
99 goes into 690 6 times with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 9008.69696
If we subtract 594 from 690, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 12:
99 goes into 960 9 times with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 9008.696969
Subtract 891 from 960 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 13:
If we divide 690 by 99, we get 6 and a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 9008.6969696
If we subtract 594 from 690, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
960 divided by 99 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 9008.69696969
If we take 891 away from 960, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 9008.69696969 and a remainder of 6.9e-08.
