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

Step 1: How do we understand the task prompting me to do?
Calculate the frequency of character "a" in the text "sesquipedalian"

Step 2: Dissect the word.
S-E-S-Q-U-I-B-X-D-A-L-I-A-N


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

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

1. S
2. E
3. S
4. Q
5. U
6. I
7. P
8. E
9. D
10. A
11. L
12. I
13. A
14. N

Step 5: Find the positions of the letter "a".
The letter "a" appears at the 10th, 13th positions in the word.

Step 6: Count the letters.
L: 1, P: 1, A: 2, E: 2, D: 1, U: 1, S: 2, I: 2, N: 1, Q: 1

Step 7: Inspect the letters we enumerated.
The target letter was "a" and there are 2 in all.
