<thinking>Let's approach this step-by-step:
We should reason through this carefully (CoT):

Step 1: What is the task requiring me to do?
Calculate the frequency of character "f" in the term "Hemoglobin"

Step 2: Separate the word.
H-E-M-O-G-L-O-B-I-N


1. H
2. E
3. M
4. O
5. G
6. L
7. O
8. B
9. I
10. N

Step 3: Determine the positions of the letter "f".
The letter "f" does not appear in the word.

Step 4: Quantify the letters.
L: 1, E: 1, G: 1, M: 1, I: 1, N: 1, H: 1, B: 1, O: 2

Step 5: Examine the letters we quantified.
The focus letter was "f" and there are 0 total.</thinking>
