We divide 609906 by 18
The aim is to understand the frequency of 18 in 609906.

Step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 18

On to step 2:
18 can be fit into 60 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 6 after subtracting 54 from 60.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 18

Going ahead to step 3:
If we divide 69 by 18, we get 3 and a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 33.0
Deduct 54 from 69 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 18

Moving on to step 4:
159 divided by 18 is 8 with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 338.0
The remainder is 15 after subtracting 144 from 159.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 18

Step 5:
The number 18 fits into 150 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 3388.0
Deduct 144 from 150 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 18

Let's proceed to step 6:
18 goes into 66 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 33883.0
If we subtract 54 from 66, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 33883.6
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 33883.66
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 33883.66 with a balance of 0.012.
