266490 divided by 18 
Our goal is to divide 266490 by 18.

On to step 1:
When dividing 2 by 18, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 18

On to step 2:
The number 18 fits into 26 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we take 18 away from 26, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 18

Moving on to step 3:
When dividing 86 by 18, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 72 from 86 to get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 18

Step 4:
18 goes into 144 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Subtracting 144 from 144 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 18

On to step 5:
The number 18 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 1480.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 18

Going ahead to step 6:
18 goes into 90 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 14805.0
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 18 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 14805.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14805.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 14805.0, and the remainder is 0.0.
