We look at the division of 288569 by 18 
The aim is to understand the frequency of 18 in 288569.

Step 1:
18 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 18

Let's proceed to step 2:
18 can be fit into 28 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 18 from 28, we get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 18

Going ahead to step 3:
When dividing 108 by 18, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 108 from 108 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 18

Going ahead to step 4:
18 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Subtract 0 from 5 to get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 18

Step 5:
18 goes into 56 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1603.0
Subtract 54 from 56 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 18

Step 6:
18 goes into 29 1 times with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 16031.0
If we take 18 away from 29, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 18, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 16031.6
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 18 fits into 20 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 16031.61
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 18 fits into 20 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 16031.611
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 16031.611 with a balance of 0.0002.
