Let's divide 133435 by 18
The aim is to understand the frequency of 18 in 133435.

Advancing to step 1:
If we divide 1 by 18, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 18

On to step 2:
When dividing 13 by 18, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 18

Step 3:
If we divide 133 by 18, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 126 from 133 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 18

On to step 4:
When dividing 74 by 18, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Subtracting 72 from 74 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 18

On to step 5:
18 goes into 23 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 741.0
Subtract 18 from 23 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 18

Let's proceed to step 6:
55 divided by 18 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 7413.0
Subtract 54 from 55 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7413.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 18, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7413.05
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 18, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7413.055
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 7413.055 with a remainder of 0.001.
