We're dividing 255222 by 54 
Let's see how many times 54 fits into 255222.

Advancing to step 1:
When dividing 2 by 54, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 54

Going ahead to step 2:
25 divided by 54 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 54

Step 3:
255 divided by 54 is 4 with a remainder of 39.
The next digit of our result is 4. 
Result so far: 4.0
If we take 216 away from 255, we end up with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 54

On to step 4:
54 can be fit into 392 7 times, resulting in a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 378 from 392 and we're left with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 54

Moving on to step 5:
When dividing 142 by 54, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 472.0
Subtract 108 from 142 to get 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 54

Step 6:
When dividing 342 by 54, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 4726.0
Deduct 324 from 342 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 54 is 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 4726.3
If we take 162 away from 180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
54 goes into 180 3 times with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 4726.33
Subtract 162 from 180 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 4726.33, and the remainder is 0.018.
