We look at the division of 478509 by 27 
Our goal is to divide 478509 by 27.

Advancing to step 1:
When dividing 4 by 27, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 27

Moving on to step 2:
47 divided by 27 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 20 after subtracting 27 from 47.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 27

On to step 3:
208 divided by 27 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 189 from 208 and we're left with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 27

Step 4:
The number 27 fits into 195 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
If we take 189 away from 195, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 27

Moving on to step 5:
The number 27 fits into 60 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1772.0
Subtracting 54 from 60 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 27

On to step 6:
If we divide 69 by 27, we get 2 and a remainder of 15.
The next digit of our result is 2. 
Result so far: 17722.0
Subtract 54 from 69 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
When dividing 150 by 27, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 17722.5
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
27 goes into 150 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 17722.55
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 17722.55 with a remaining 0.015.
