1. **State the problem:** Simplify the expression $$\frac{(16)^{-2}}{(4^{-1})^2}$$.
2. **Recall the exponent rules:**
- For any nonzero number $a$ and integers $m,n$, $a^{-m} = \frac{1}{a^m}$.
- Power of a power: $(a^m)^n = a^{mn}$.
- Division of powers with the same base: $\frac{a^m}{a^n} = a^{m-n}$.
3. **Simplify numerator:**
$$16^{-2} = \frac{1}{16^2} = \frac{1}{256}$$
4. **Simplify denominator:**
$$(4^{-1})^2 = 4^{-2} = \frac{1}{4^2} = \frac{1}{16}$$
5. **Rewrite the expression:**
$$\frac{\frac{1}{256}}{\frac{1}{16}}$$
6. **Divide fractions by multiplying numerator by reciprocal of denominator:**
$$\frac{1}{256} \times \frac{16}{1} = \frac{16}{256}$$
7. **Simplify the fraction:**
$$\frac{16}{256} = \frac{\cancel{16}^1}{\cancel{16}^{16}} = \frac{1}{16}$$
**Final answer:** $$\frac{1}{16}$$
