126081 ÷ 27 
We want to divide 126081 by 27.

On to step 1:
27 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 27

Advancing to step 2:
27 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 27

Step 3:
The number 27 fits into 126 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 108 from 126 to get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 27

On to step 4:
The number 27 fits into 180 6 times, leaving a remainder of 18.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 162 from 180, we get 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 27

Advancing to step 5:
The number 27 fits into 188 6 times, leaving a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 466.0
The remainder is 26 after subtracting 162 from 188.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 27

Advancing to step 6:
The number 27 fits into 261 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 4669.0
If we take 243 away from 261, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 27 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 4669.6
If we take 162 away from 180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
27 can be fit into 180 6 times, resulting in a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 4669.66
If we subtract 162 from 180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 4669.66, and the remainder is 0.018.
