Let's divide 107391 by 27
We want to divide 107391 by 27.

Step 1:
27 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 27

Step 2:
27 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 27

Let's proceed to step 3:
The number 27 fits into 107 3 times, leaving a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 26 after subtracting 81 from 107.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 27

Step 4:
The number 27 fits into 263 9 times, leaving a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 243 away from 263, we end up with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 27

Step 5:
If we divide 209 by 27, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 397.0
Deduct 189 from 209 and we're left with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 27

On to step 6:
201 divided by 27 is 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 3977.0
If we take 189 away from 201, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
27 goes into 120 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 3977.4
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
27 goes into 120 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 3977.44
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 3977.44, and the remainder is 0.012.
