We're dividing 69430 by 18 
The aim is to understand the frequency of 18 in 69430.

Going ahead to step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 18

Let's proceed to step 2:
69 divided by 18 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 54 from 69 leaves us with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 18

Step 3:
18 can be fit into 154 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 144 from 154, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 18

Going ahead to step 4:
18 goes into 103 5 times with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 385.0
If we subtract 90 from 103, we get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 18

Moving on to step 5:
130 divided by 18 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 3857.0
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 6:
The number 18 fits into 40 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3857.2
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
18 goes into 40 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 3857.22
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 3857.22 with a remaining 0.004.
