663206 ÷ 18 
Our goal is to divide 663206 by 18.

On to step 1:
6 divided by 18 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 18

Advancing to step 2:
18 can be fit into 66 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 54 away from 66, we end up with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 18

On to step 3:
The number 18 fits into 123 6 times, leaving a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 108 from 123 to get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 18

Let's proceed to step 4:
18 goes into 152 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 368.0
Subtracting 144 from 152 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 18

Going ahead to step 5:
80 divided by 18 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3684.0
If we take 72 away from 80, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 18

Going ahead to step 6:
When dividing 86 by 18, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 36844.0
If we take 72 away from 86, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
140 divided by 18 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 36844.7
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
140 divided by 18 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 36844.77
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 36844.77 with a remaining 0.014.
