660522 divided by 18 
We want to figure out the number of times 660522 can be divided by 18.

Step 1:
6 divided by 18 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 18

Step 2:
66 divided by 18 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 54 from 66 leaves us with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 18

Advancing to step 3:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 36.0
If we take 108 away from 120, we end up with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 18

Let's proceed to step 4:
The number 18 fits into 125 6 times, leaving a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 366.0
If we subtract 108 from 125, we get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 18

Going ahead to step 5:
18 goes into 172 9 times with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 3669.0
Deduct 162 from 172 and we're left with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 18

Going ahead to step 6:
102 divided by 18 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 36695.0
Subtract 90 from 102 to get 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:
If we divide 120 by 18, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 36695.6
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 18, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 36695.66
If we subtract 108 from 120, we get 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 36695.66, and the remainder is 0.012.
