We look at the division of 272939 by 30 
The aim is to understand the frequency of 30 in 272939.

Step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 30

On to step 2:
If we divide 27 by 30, we get 0 and a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Take the next digit (2) from the dividend and append it to 27, then repeat: 272 / 30

Let's proceed to step 3:
272 divided by 30 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 270 from 272 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 30

Moving on to step 4:
The number 30 fits into 29 0 times, leaving a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 29 to get 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 30

Step 5:
30 can be fit into 293 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 909.0
If we subtract 270 from 293, we get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 30

Let's proceed to step 6:
When dividing 239 by 30, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 9097.0
Subtracting 210 from 239 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
The number 30 fits into 290 9 times, leaving a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 9097.9
Deduct 270 from 290 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 30 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 9097.96
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 9097.966
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 9097.966, with a leftover of 0.002.
