1. **State the problem:** Simplify the expression $\left(\frac{4^2}{2^2} + 3^2\right) \div 13 + \left(5^2 - 2^4 - 5\right)^2 - 3^2$.
2. **Calculate powers:**
- $4^2 = 16$
- $2^2 = 4$
- $3^2 = 9$
- $5^2 = 25$
- $2^4 = 16$
3. **Simplify inside the parentheses:**
- $\frac{4^2}{2^2} = \frac{16}{4} = \cancel{\frac{16}{4}}{4}$
- So, $\frac{4^2}{2^2} + 3^2 = 4 + 9 = 13$
4. **Divide by 13:**
- $\left(4 + 9\right) \div 13 = 13 \div 13 = \cancel{\frac{13}{13}}{1}$
5. **Simplify the second parentheses:**
- $5^2 - 2^4 - 5 = 25 - 16 - 5 = 9 - 5 = 4$
6. **Square the result:**
- $4^2 = 16$
7. **Subtract $3^2$:**
- $16 - 9 = 7$
8. **Add the two parts:**
- $1 + 7 = 8$
**Final answer:** $8$
