We look at the division of 857703 by 54 
We're looking to find how many times 54 goes into 857703.

Going ahead to step 1:
The number 54 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 54

Moving on to step 2:
If we divide 85 by 54, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 54 from 85, we get 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 54

Step 3:
54 can be fit into 317 5 times, resulting in a remainder of 47.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 270 from 317 leaves us with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 54

Step 4:
54 can be fit into 477 8 times, resulting in a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtracting 432 from 477 leaves us with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 54

Going ahead to step 5:
450 divided by 54 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 1588.0
If we take 432 away from 450, we end up with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 54

Advancing to step 6:
If we divide 183 by 54, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 15883.0
Deduct 162 from 183 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
If we divide 210 by 54, we get 3 and a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 15883.3
Subtracting 162 from 210 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.

On to step 8:
480 divided by 54 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 15883.38
If we take 432 away from 480, we end up 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.

On to step 9:
480 divided by 54 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 15883.388
If we subtract 432 from 480, we 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.

The quotient of the division is 15883.388, and the remainder is 0.0048.
