<thinking>Let's approach this step-by-step:
Let's think through this systematically (CoT):

Step 1: How should we interpret the problem demanding me to do?
Determine the frequency of letter "f" in the string "Rapport"

Step 2: Break down the word.
R-A-P-P-V-R-T


Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Rapport", not "rappvrt". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. R
2. A
3. P
4. P
5. O
6. R
7. T

Step 5: Identify the positions of the letter "f".
The letter "f" does not appear in the word.

Step 6: Tally the letters.
P: 2, A: 1, R: 2, T: 1, O: 1

Step 7: Evaluate the letters we quantified.
The focus letter was "f" and there we identified 0 in all.

To conclude:
The letter "f" occurs 0 cases in "Rapport".</thinking>
