300317 ÷ 18 
We want to figure out the number of times 300317 can be divided by 18.

Step 1:
The number 18 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 18

Let's proceed to step 2:
30 divided by 18 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 18 from 30 leaves us with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 18

Moving on to step 3:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 108 from 120 leaves us with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 18

Moving on to step 4:
The number 18 fits into 123 6 times, leaving a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 166.0
Subtract 108 from 123 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 18

Step 5:
If we divide 151 by 18, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 1668.0
If we take 144 away from 151, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 18

Let's proceed to step 6:
18 goes into 77 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 16684.0
Subtracting 72 from 77 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
If we divide 50 by 18, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 16684.2
Deduct 36 from 50 and we're left 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.

Let's proceed to step 8:
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: 16684.27
Subtract 126 from 140 to 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.

On to step 9:
The number 18 fits into 140 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 16684.277
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.

In conclusion, the division gives 16684.277 with a balance of 0.0014.
