We look at the division of 108690 by 27 
We want to figure out the number of times 108690 can be divided by 27.

Let's proceed to step 1:
When dividing 1 by 27, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 27

Step 2:
If we divide 10 by 27, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 27

Moving on to step 3:
When dividing 108 by 27, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 0 after subtracting 108 from 108.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 27

Advancing to step 4:
27 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 27

Advancing to step 5:
69 divided by 27 is 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
Subtracting 54 from 69 leaves us with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 27

On to step 6:
If we divide 150 by 27, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4025.0
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 27, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4025.5
Deduct 135 from 150 and we're left 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.

Moving on to step 8:
When dividing 150 by 27, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 4025.55
Deduct 135 from 150 and we're left 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.

The quotient of the division is 4025.55, and the remainder is 0.015.
