304515 ÷ 97 
The aim is to understand the frequency of 97 in 304515.

Moving on to step 1:
97 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 97

Let's proceed to step 2:
When dividing 30 by 97, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 97

Step 3:
The number 97 fits into 304 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 291 from 304 leaves us with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 97

On to step 4:
135 divided by 97 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 97 from 135 to get 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 97

Step 5:
97 goes into 381 3 times with a remainder of 90.
The next digit of our result is 3. 
Result so far: 313.0
Deduct 291 from 381 and we're left with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 97

Moving on to step 6:
When dividing 905 by 97, we get 9 with a remainder of 32.
The next digit of our result is 9. 
Result so far: 3139.0
Subtracting 873 from 905 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
The number 97 fits into 320 3 times, leaving a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 3139.3
The remainder is 29 after subtracting 291 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 8:
When dividing 290 by 97, we get 2 with a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 3139.32
The remainder is 96 after subtracting 194 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
The number 97 fits into 960 9 times, leaving a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 3139.329
If we subtract 873 from 960, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 10:
When dividing 870 by 97, we get 8 with a remainder of 94.
Put 8 as the next digit of the answer. 
Result so far: 3139.3298
Subtract 776 from 870 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 11:
The number 97 fits into 940 9 times, leaving a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 3139.32989
Subtracting 873 from 940 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 12:
When dividing 670 by 97, we get 6 with a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 3139.329896
If we take 582 away from 670, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
97 can be fit into 880 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 3139.3298969
Deduct 873 from 880 and we're left 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.

On to step 14:
If we divide 70 by 97, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 3139.3298969
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 3139.3298969 with a remainder of 7e-08.
