We're dividing 663494 by 18 
Our goal is to divide 663494 by 18.

Moving on to step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 18

Advancing to step 2:
If we divide 66 by 18, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 54 from 66 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 18

On to step 3:
18 can be fit into 123 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 36.0
If we subtract 108 from 123, we get 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 18

Let's proceed to step 4:
154 divided by 18 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 368.0
If we take 144 away from 154, we end up with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 18

Let's proceed to step 5:
When dividing 109 by 18, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 3686.0
The remainder is 1 after subtracting 108 from 109.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 18

On to step 6:
18 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 36860.0
If we take 0 away from 14, 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.

Moving on to step 7:
When dividing 140 by 18, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 36860.7
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.

Step 8:
140 divided by 18 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 36860.77
If we take 126 away from 140, 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.

Our division results in 36860.77 with a remaining 0.014.
