The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 54

Moving on to step 2:
When dividing 64 by 54, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 54 from 64 and we're left with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 54

On to step 3:
54 goes into 105 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 54 from 105 to get 51.

The number 54 fits into 334 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 1196.0
If we subtract 324 from 334, we get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 54

Going ahead to step 6:
54 goes into 108 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 11962.0
The remainder is 0 after subtracting 108 from 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
54 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11962.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 54 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11962.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 11962.0 with a remaining 0.0.
