1. The problem is to simplify the expression $\frac{30}{5} \div 2$. 2. Recall that division of fractions or numbers can be rewritten as multiplication by the reciprocal: $a \div b = a \times \frac{1}{b}$. 3. First, simplify $\frac{30}{5}$: $$\frac{30}{5} = 6$$ 4. Now rewrite the division by 2 as multiplication by $\frac{1}{2}$: $$6 \div 2 = 6 \times \frac{1}{2}$$ 5. Multiply: $$6 \times \frac{1}{2} = \frac{6}{2}$$ 6. Simplify the fraction by canceling common factors: $$\frac{\cancel{6}}{\cancel{2}} = 3$$ 7. Therefore, the final answer is $3$.
