We divide 196566 by 18
The aim is to understand the frequency of 18 in 196566.

Going ahead to step 1:
The number 18 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 18

Going ahead to step 2:
19 divided by 18 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 18 from 19.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 18

On to step 3:
18 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 18

Let's proceed to step 4:
If we divide 165 by 18, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
The remainder is 3 after subtracting 162 from 165.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 18

Moving on to step 5:
18 can be fit into 36 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 1092.0
The remainder is 0 after subtracting 36 from 36.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 18

Advancing to step 6:
The number 18 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 10920.0
The remainder is 6 after subtracting 0 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 18, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 10920.3
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
18 goes into 60 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 10920.33
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 10920.33 with a remainder of 0.006.
