Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 10:
If we divide 4540 by 648, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 49013.77
If we take 4536 away from 4540, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 49013.77 with a balance of 0.004.
