54 goes into 320 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 502564.75
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
54 goes into 500 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 502564.759
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
54 goes into 140 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 502564.7592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
When dividing 320 by 54, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 502564.75925
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
500 divided by 54 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 502564.759259
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 15:
When dividing 140 by 54, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 502564.7592592
Deduct 108 from 140 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
