391887 divided by 54 
We want to divide 391887 by 54.

On to step 1:
3 divided by 54 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 54

Step 2:
If we divide 39 by 54, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 54

Moving on to step 3:
The number 54 fits into 391 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 7.0
If we take 378 away from 391, we end up with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 54

Step 4:
54 can be fit into 138 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 108 from 138 and we're left with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 54

On to step 5:
When dividing 308 by 54, we get 5 with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 725.0
If we subtract 270 from 308, we get 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 54

Moving on to step 6:
54 can be fit into 387 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7257.0
If we take 378 away from 387, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 54 fits into 90 1 times, leaving a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 7257.1
If we take 54 away from 90, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
The number 54 fits into 360 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 7257.16
If we subtract 324 from 360, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
54 goes into 360 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 7257.166
The remainder is 36 after subtracting 324 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 7257.166 with a remaining 0.0036.
