Going ahead to step 8:
The number 478 fits into 535 1 times, leaving a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 162981.0
If we subtract 478 from 535, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
The number 478 fits into 570 1 times, leaving a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 162981.1
The remainder is 92 after subtracting 478 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
The number 478 fits into 920 1 times, leaving a remainder of 442.
The number 1 becomes the next digit in our result. 
Result so far: 162981.11
Subtract 478 from 920 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

In conclusion, the division gives 162981.11 with a balance of 0.442.
