We're dividing 815772 by 54 
We want to divide 815772 by 54.

Going ahead to step 1:
54 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 54

Moving on to step 2:
81 divided by 54 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 27 after subtracting 54 from 81.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 54

Let's proceed to step 3:
54 goes into 275 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 270 from 275 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 54

Step 4:
When dividing 57 by 54, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 151.0
Subtracting 54 from 57 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 54

Let's proceed to step 5:
When dividing 37 by 54, we get 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 1510.0
Subtract 0 from 37 to get 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 54

On to step 6:
If we divide 372 by 54, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 15106.0
Subtract 324 from 372 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
480 divided by 54 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 15106.8
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
When dividing 480 by 54, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 15106.88
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 15106.88 with a remaining 0.048.
