Let's divide 339303 by 18
Our goal is to divide 339303 by 18.

Moving on to step 1:
When dividing 3 by 18, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 18

On to step 2:
33 divided by 18 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 18 away from 33, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 18

Let's proceed to step 3:
18 goes into 159 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 144 from 159, we get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 18

Let's proceed to step 4:
The number 18 fits into 153 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Subtract 144 from 153 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 18

Going ahead to step 5:
When dividing 90 by 18, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1885.0
Subtract 90 from 90 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 18

On to step 6:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 18850.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 18, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 18850.1
If we take 18 away from 30, we end up with 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:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 18850.16
If we take 108 away from 120, we end up with 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 9:
120 divided by 18 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 18850.166
Subtracting 108 from 120 leaves us with 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 final outcome is 18850.166, with a leftover of 0.0012.
