We're dividing 510855 by 54 
We want to figure out the number of times 510855 can be divided by 54.

Going ahead to step 1:
54 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 54

Step 2:
If we divide 51 by 54, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 54

Going ahead to step 3:
54 can be fit into 510 9 times, resulting in a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 24 after subtracting 486 from 510.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 54

Going ahead to step 4:
54 goes into 248 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Deduct 216 from 248 and we're left with 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 54

Moving on to step 5:
The number 54 fits into 325 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 946.0
If we subtract 324 from 325, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 54

On to step 6:
The number 54 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 9460.0
The remainder is 15 after subtracting 0 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
54 can be fit into 150 2 times, resulting in a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 9460.2
Subtracting 108 from 150 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
When dividing 420 by 54, we get 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 9460.27
If we take 378 away from 420, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
54 can be fit into 420 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 9460.277
The remainder is 42 after subtracting 378 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 9460.277 with a remaining 0.0042.
