We look at the division of 912747 by 30 
The aim is to understand the frequency of 30 in 912747.

Going ahead to step 1:
When dividing 9 by 30, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 30

Going ahead to step 2:
When dividing 91 by 30, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 90 from 91 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 30

On to step 3:
If we divide 12 by 30, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 30

Let's proceed to step 4:
If we divide 127 by 30, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 304.0
The remainder is 7 after subtracting 120 from 127.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 30

Advancing to step 5:
When dividing 74 by 30, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 3042.0
The remainder is 14 after subtracting 60 from 74.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 30

Going ahead to step 6:
The number 30 fits into 147 4 times, leaving a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 30424.0
Subtracting 120 from 147 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
30 goes into 270 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 30424.9
If we take 270 away from 270, we end up 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.

On to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30424.9
If we take 0 away from 0, we end up 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.

Step 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30424.9
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.

The final result is 30424.9 with a remainder of 0.0.
