We look at the division of 353369 by 18 
We want to figure out the number of times 353369 can be divided by 18.

Let's proceed to step 1:
3 divided by 18 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 18

Let's proceed to step 2:
18 can be fit into 35 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 18 from 35 to get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 18

Moving on to step 3:
18 goes into 173 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 162 from 173 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 18

Moving on to step 4:
When dividing 113 by 18, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 196.0
If we subtract 108 from 113, we get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 18

Moving on to step 5:
If we divide 56 by 18, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1963.0
Subtract 54 from 56 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 18

Going ahead to step 6:
29 divided by 18 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 19631.0
The remainder is 11 after subtracting 18 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 18, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 19631.6
If we subtract 108 from 110, 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.

Advancing to step 8:
The number 18 fits into 20 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 19631.61
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 9:
20 divided by 18 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 19631.611
Subtracting 18 from 20 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.

The final result is 19631.611 with a remainder of 0.0002.
