We look at the division of 730297 by 15 
The aim is to understand the frequency of 15 in 730297.

Moving on to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 15

Moving on to step 2:
15 can be fit into 73 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 60 from 73 leaves us with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 15

Going ahead to step 3:
130 divided by 15 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 120 from 130 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 15

On to step 4:
The number 15 fits into 102 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 486.0
Deduct 90 from 102 and we're left with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 15

Going ahead to step 5:
The number 15 fits into 129 8 times, leaving a remainder of 9.
The next digit of our result is 8. 
Result so far: 4868.0
If we take 120 away from 129, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 15

Let's proceed to step 6:
If we divide 97 by 15, we get 6 and a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 48686.0
If we take 90 away from 97, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 15, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 48686.4
Subtract 60 from 70 to 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 8:
15 goes into 100 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 48686.46
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 15 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 48686.466
The remainder is 10 after subtracting 90 from 100.
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 48686.466 with a remainder of 0.001.
