Let's divide 408396 by 27
We want to figure out the number of times 408396 can be divided by 27.

Going ahead to step 1:
If we divide 4 by 27, we get 0 and 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.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 27

Moving on to step 2:
If we divide 40 by 27, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 27 from 40, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 27

Let's proceed to step 3:
When dividing 138 by 27, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 135 from 138, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 27

Let's proceed to step 4:
When dividing 33 by 27, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Subtracting 27 from 33 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 27

Going ahead to step 5:
69 divided by 27 is 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 1512.0
Subtract 54 from 69 to get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 27

Advancing to step 6:
If we divide 156 by 27, we get 5 and a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 15125.0
If we subtract 135 from 156, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
27 can be fit into 210 7 times, resulting in a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 15125.7
If we subtract 189 from 210, we get 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:
When dividing 210 by 27, we get 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 15125.77
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.

Our division results in 15125.77 with a remaining 0.021.
