On to step 2:
27 can be fit into 55 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 54 from 55 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 27

Let's proceed to step 3:
27 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 11, we get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 27

Going ahead to step 4:
The number 27 fits into 111 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 204.0
Subtracting 108 from 111 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 27

Put 1 as the next digit of the answer. 
Result so far: 2041.0
Subtracting 27 from 37 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 27

On to step 6:
If we divide 102 by 27, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 20413.0
The remainder is 21 after subtracting 81 from 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
210 divided by 27 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 20413.7
Subtracting 189 from 210 leaves us 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 8:
27 goes into 210 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 20413.77
If we take 189 away from 210, we end up 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.

Our division results in 20413.77 with a remaining 0.021.
