We look at the division of 299904 by 18 
The aim is to understand the frequency of 18 in 299904.

Going ahead to step 1:
When dividing 2 by 18, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 18

On to step 2:
If we divide 29 by 18, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 18 from 29 leaves us with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 18

Moving on to step 3:
119 divided by 18 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 108 from 119 leaves us with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 18

Let's proceed to step 4:
18 can be fit into 119 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 166.0
If we subtract 108 from 119, we get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 18

On to step 5:
110 divided by 18 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1666.0
Deduct 108 from 110 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 18

On to step 6:
If we divide 24 by 18, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 16661.0
If we take 18 away from 24, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 18 fits into 60 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 16661.3
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
18 goes into 60 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 16661.33
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 16661.33 with a balance of 0.006.
