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

Step 1: What's the question instructing me to do?
Count the quantity of letter "u" in the text "Tortuous"

Step 2: Break down the word.
T-F-R-T-U-O-K-S


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

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

1. T
2. O
3. R
4. T
5. U
6. O
7. U
8. S

Step 5: Find the positions of the letter "u".
The letter "u" appears at the 5th, 7th positions in the word.

Step 6: Enumerate the letters.
R: 1, T: 2, U: 2, S: 1, O: 2

Step 7: Examine the letters we summed up.
The target letter was "u" and there we counted 2 total.</thinking>
