We look at the division of 240590 by 18 
We want to divide 240590 by 18.

Going ahead to step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 18

Moving on to step 2:
18 goes into 24 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 18 from 24 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 18

Advancing to step 3:
If we divide 60 by 18, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 6 after subtracting 54 from 60.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 18

On to step 4:
When dividing 65 by 18, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 133.0
Subtract 54 from 65 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 18

Going ahead to step 5:
If we divide 119 by 18, we get 6 and a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 1336.0
Subtracting 108 from 119 leaves us with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 18

On to step 6:
110 divided by 18 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 13366.0
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 18 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 13366.1
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 18, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 13366.11
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 13366.11, and the remainder is 0.002.
