We're dividing 5115 by 54 
We're looking to find how many times 54 goes into 5115.

Let's proceed to step 1:
The number 54 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 54

Moving on to step 2:
54 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 54

On to step 3:
If we divide 511 by 54, we get 9 and a remainder of 25.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 486 from 511 to get 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 54

Advancing to step 4:
The number 54 fits into 255 4 times, leaving a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtracting 216 from 255 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 5:
When dividing 390 by 54, we get 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 94.7
Subtracting 378 from 390 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 6:
120 divided by 54 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 94.72
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
If we divide 120 by 54, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 94.722
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 94.722 and a remainder of 0.0012.
