Let's divide 212928 by 99
We're looking to find how many times 99 goes into 212928.

Going ahead to step 1:
The number 99 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 99

Step 2:
99 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 99

Advancing to step 3:
99 goes into 212 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 198 away from 212, we end up with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 99

On to step 4:
If we divide 149 by 99, we get 1 and a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 99 away from 149, we end up with 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 99

Advancing to step 5:
The number 99 fits into 502 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 215.0
If we take 495 away from 502, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 99

Going ahead to step 6:
99 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 2150.0
Subtract 0 from 78 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 7:
The number 99 fits into 780 7 times, leaving a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 2150.7
If we subtract 693 from 780, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 8:
The number 99 fits into 870 8 times, leaving a remainder of 78.
The next digit of our result is 8. 
Result so far: 2150.78
Subtracting 792 from 870 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
780 divided by 99 is 7 with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 2150.787
If we take 693 away from 780, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 10:
The number 99 fits into 870 8 times, leaving a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 2150.7878
Subtract 792 from 870 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
99 goes into 780 7 times with a remainder of 87.
The next digit of our result is 7. 
Result so far: 2150.78787
Deduct 693 from 780 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 12:
99 can be fit into 870 8 times, resulting in a remainder of 78.
The next digit of our result is 8. 
Result so far: 2150.787878
If we take 792 away from 870, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 13:
780 divided by 99 is 7 with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 2150.7878787
Subtract 693 from 780 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 14:
The number 99 fits into 870 8 times, leaving a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 2150.78787878
The remainder is 78 after subtracting 792 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 2150.78787878 with a remainder of 7.8e-08.
