We're dividing 2640 by 18 
Our goal is to divide 2640 by 18.

Advancing to step 1:
2 divided by 18 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 18

Going ahead to step 2:
18 goes into 26 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 18 from 26, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 18

Going ahead to step 3:
84 divided by 18 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 12 after subtracting 72 from 84.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 18

Going ahead to step 4:
When dividing 120 by 18, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 146.0
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.

Going ahead to step 5:
When dividing 120 by 18, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 146.6
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.

Step 6:
If we divide 120 by 18, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.66
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.

After the division, we end up with 146.66 and a remainder of 0.012.
