We look at the division of 297075 by 18 
The aim is to understand the frequency of 18 in 297075.

Step 1:
2 divided by 18 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 18

Advancing 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
If we take 18 away from 29, we end up with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 18

Moving on to step 3:
The number 18 fits into 117 6 times, leaving a remainder of 9.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 108 from 117 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 18

On to step 4:
90 divided by 18 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 165.0
The remainder is 0 after subtracting 90 from 90.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 18

Let's proceed to step 5:
7 divided by 18 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 1650.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 18

Advancing to step 6:
18 goes into 75 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 16504.0
The remainder is 3 after subtracting 72 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 18, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 16504.1
Deduct 18 from 30 and we're left 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.

Let's proceed to step 8:
18 goes into 120 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 16504.16
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
18 goes into 120 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 16504.166
Deduct 108 from 120 and we're left 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.

In conclusion, the division gives 16504.166 with a balance of 0.0012.
