488123 ÷ 99 
Let's see how many times 99 fits into 488123.

Advancing to step 1:
99 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 99

On to step 2:
When dividing 48 by 99, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 99

Step 3:
488 divided by 99 is 4 with a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 396 from 488 and we're left with 92.
Append the next digit (1) from the dividend to 92 and continue with: 921 / 99

Moving on to step 4:
The number 99 fits into 921 9 times, leaving a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Deduct 891 from 921 and we're left with 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 99

On to step 5:
When dividing 302 by 99, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 493.0
Deduct 297 from 302 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 99

Advancing to step 6:
99 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 4930.0
The remainder is 53 after subtracting 0 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
99 can be fit into 530 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4930.5
If we take 495 away from 530, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
The number 99 fits into 350 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 4930.53
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
530 divided by 99 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 4930.535
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
350 divided by 99 is 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 4930.5353
If we subtract 297 from 350, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
When dividing 530 by 99, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 4930.53535
If we take 495 away from 530, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
99 goes into 350 3 times with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 4930.535353
The remainder is 53 after subtracting 297 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 13:
When dividing 530 by 99, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4930.5353535
If we take 495 away from 530, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
The number 99 fits into 350 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 4930.53535353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 4930.53535353 and a remainder of 5.3e-08.
