We divide 851772 by 54
We're looking to find how many times 54 goes into 851772.

Let's proceed to step 1:
54 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 54

Going ahead to step 2:
54 can be fit into 85 1 times, resulting in a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 31 after subtracting 54 from 85.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 54

Advancing to step 3:
The number 54 fits into 311 5 times, leaving a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 270 from 311 to get 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 54

Advancing to step 4:
If we divide 417 by 54, we get 7 and a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtracting 378 from 417 leaves us with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 54

Advancing to step 5:
397 divided by 54 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 1577.0
Deduct 378 from 397 and we're left with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 54

Moving on to step 6:
The number 54 fits into 192 3 times, leaving a remainder of 30.
The next digit of our result is 3. 
Result so far: 15773.0
The remainder is 30 after subtracting 162 from 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 54, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15773.5
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
54 can be fit into 300 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15773.55
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 15773.55, with a leftover of 0.03.
