We divide 815808 by 27
We're looking to find how many times 27 goes into 815808.

Step 1:
If we divide 8 by 27, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 27

Advancing to step 2:
When dividing 81 by 27, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 81 from 81 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 27

Step 3:
If we divide 5 by 27, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 5, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 27

On to step 4:
27 can be fit into 58 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 302.0
Deduct 54 from 58 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 27

On to step 5:
27 can be fit into 40 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 3021.0
Subtracting 27 from 40 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 27

Moving on to step 6:
If we divide 138 by 27, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 30215.0
If we subtract 135 from 138, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 27, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 30215.1
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
The number 27 fits into 30 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 30215.11
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 30215.11 with a remainder of 0.003.
