1. **State the problem:** We are given that $\frac{1}{3}$ of a shape is shaded, and we need to calculate $\frac{1}{3} \div 2$. 2. **Recall the division rule for fractions:** Dividing by a number is the same as multiplying by its reciprocal. So, $$\frac{1}{3} \div 2 = \frac{1}{3} \times \frac{1}{2}$$ 3. **Multiply the fractions:** Multiply the numerators and denominators: $$\frac{1}{3} \times \frac{1}{2} = \frac{1 \times 1}{3 \times 2} = \frac{1}{6}$$ 4. **Interpretation:** The result $\frac{1}{6}$ means that one-sixth of the whole shape corresponds to $\frac{1}{3}$ divided by 2. **Final answer:** $$\boxed{\frac{1}{6}}$$
