Advancing to step 9:
54 can be fit into 440 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 9655.148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 54, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 9655.1481
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
The number 54 fits into 260 4 times, leaving a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 9655.14814
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
440 divided by 54 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 9655.148148
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 54 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 9655.1481481
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
When dividing 260 by 54, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 9655.14814814
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 9655.14814814 with a remainder of 4.4e-08.
