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

Step 1: How do we understand the problem demanding me to do?
Determine the occurrence of letter "s" in the text "Pulchritudinous"

Step 2: Separate the word.
P-U-J-S-U-R-I-H-U-D-I-N-O-U-S


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

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

1. P
2. U
3. L
4. C
5. H
6. R
7. I
8. T
9. U
10. D
11. I
12. N
13. O
14. U
15. S

Step 5: Identify the positions of the letter "s".
The letter "s" appears at the 15th position in the word.

Step 6: Sum up the letters.
L: 1, P: 1, R: 1, T: 1, D: 1, U: 3, S: 1, I: 2, N: 1, H: 1, O: 1, C: 1

Step 7: Evaluate the letters we enumerated.
The chosen letter was "s" and there were 1 overall.

Result:
The letter "s" occurs 1 case in "Pulchritudinous", at the 15th position.</thinking>
