We look at the division of 855864 by 54 
We want to figure out the number of times 855864 can be divided by 54.

On to step 1:
54 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 54

Going ahead to step 2:
54 can be fit into 85 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 54 from 85 leaves us with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 54

Going ahead to step 3:
315 divided by 54 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 270 from 315 and we're left with 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 54

Going ahead to step 4:
54 goes into 458 8 times with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 158.0
The remainder is 26 after subtracting 432 from 458.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 54

On to step 5:
266 divided by 54 is 4 with a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 1584.0
The remainder is 50 after subtracting 216 from 266.
Take the next digit (4) from the dividend and append it to 50, then repeat: 504 / 54

Advancing to step 6:
54 can be fit into 504 9 times, resulting in a remainder of 18.
The next digit of our result is 9. 
Result so far: 15849.0
If we take 486 away from 504, 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.

Let's proceed to step 7:
54 goes into 180 3 times with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 15849.3
Subtracting 162 from 180 leaves us 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.

Advancing to step 8:
If we divide 180 by 54, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 15849.33
If we subtract 162 from 180, we 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 15849.33, and the remainder is 0.018.
