We're dividing 269971 by 18 
The aim is to understand the frequency of 18 in 269971.

On to step 1:
18 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 18

Going ahead to step 2:
If we divide 26 by 18, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 18 from 26 and we're left with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 18

Step 3:
89 divided by 18 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 72 away from 89, we end up with 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 18

Advancing to step 4:
18 goes into 179 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 149.0
If we subtract 162 from 179, we get 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 18

Moving on to step 5:
177 divided by 18 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 1499.0
Subtracting 162 from 177 leaves us with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 18

Moving on to step 6:
151 divided by 18 is 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 14998.0
Subtract 144 from 151 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 18 fits into 70 3 times, leaving a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 14998.3
Subtract 54 from 70 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
When dividing 160 by 18, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 14998.38
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
18 goes into 160 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 14998.388
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 14998.388 with a remaining 0.0016.
