636618 divided by 54 
Let's see how many times 54 fits into 636618.

Moving on to step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 54

Moving on to step 2:
If we divide 63 by 54, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 9 after subtracting 54 from 63.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 54

Advancing to step 3:
54 goes into 96 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 54 from 96, we get 42.
Take the next digit (6) from the dividend and append it to 42, then repeat: 426 / 54

Moving on to step 4:
54 can be fit into 426 7 times, resulting in a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Deduct 378 from 426 and we're left with 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 54

Going ahead to step 5:
The number 54 fits into 481 8 times, leaving a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 1178.0
If we subtract 432 from 481, we get 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 54

Step 6:
The number 54 fits into 498 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 11789.0
If we take 486 away from 498, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 54 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 11789.2
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
If we divide 120 by 54, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 11789.22
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 11789.22 with a remaining 0.012.
