We're dividing 239922 by 30 
The aim is to understand the frequency of 30 in 239922.

Step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 30

Going ahead to step 2:
30 can be fit into 23 0 times, resulting in a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 30

Going ahead to step 3:
The number 30 fits into 239 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 210 from 239 and we're left with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 30

Advancing to step 4:
The number 30 fits into 299 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 79.0
The remainder is 29 after subtracting 270 from 299.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 30

Going ahead to step 5:
292 divided by 30 is 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 799.0
The remainder is 22 after subtracting 270 from 292.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 30

On to step 6:
222 divided by 30 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7997.0
Subtract 210 from 222 to 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.

On to step 7:
When dividing 120 by 30, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 7997.4
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
30 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7997.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7997.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 7997.4 with a remaining 0.0.
