We're dividing 393939 by 27 
We want to divide 393939 by 27.

Moving on to step 1:
The number 27 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 27

On to step 2:
27 goes into 39 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 27 from 39, we get 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 27

Moving on to step 3:
When dividing 123 by 27, we get 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 15 after subtracting 108 from 123.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 27

On to step 4:
27 can be fit into 159 5 times, resulting in a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 145.0
If we take 135 away from 159, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 27

Advancing to step 5:
When dividing 243 by 27, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1459.0
Subtract 243 from 243 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 27

Going ahead to step 6:
When dividing 9 by 27, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 14590.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 27, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 14590.3
Subtracting 81 from 90 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
27 goes into 90 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 14590.33
The remainder is 9 after subtracting 81 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 14590.33 with a remainder of 0.009.
