We're dividing 863340 by 27 
We want to divide 863340 by 27.

Advancing to step 1:
27 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 27

Going ahead to step 2:
27 goes into 86 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 81 from 86 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 27

Going ahead to step 3:
The number 27 fits into 53 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 27 from 53 and we're left with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 27

Step 4:
263 divided by 27 is 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 319.0
The remainder is 20 after subtracting 243 from 263.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 27

On to step 5:
If we divide 204 by 27, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 3197.0
If we subtract 189 from 204, we get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 27

Going ahead to step 6:
27 can be fit into 150 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 31975.0
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.

Going ahead to 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: 31975.5
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.

On to step 8:
When dividing 150 by 27, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 31975.55
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 final result is 31975.55 with a remainder of 0.015.
