Going ahead to step 9:
4550 divided by 999 is 4 with a remainder of 554.
The next digit of our result is 4. 
Result so far: 30255.4
The remainder is 554 after subtracting 3996 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 10:
If we divide 5540 by 999, we get 5 and a remainder of 545.
Put 5 as the next digit of the answer. 
Result so far: 30255.45
Subtract 4995 from 5540 to get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Moving on to step 11:
If we divide 5450 by 999, we get 5 and a remainder of 455.
The next digit of our result is 5. 
Result so far: 30255.455
The remainder is 455 after subtracting 4995 from 5450.
