Explanation:

Step1: Solve $72 \div 4$ via long division

Divide tens place: $7 \div 4 = 1$, remainder $3$. Bring down 2 to get $32$.
$32 \div 4 = 8$. Combine results: $10 + 8 = 18$

$$\begin{array}{r} 18 \\ 4\enclose{longdiv}{72} \\ \underline{-4}\phantom{2} \\ 32 \\ \underline{-32} \\ 0 \end{array}$$

Step2: Solve $96 \div 3$ via long division

Divide tens place: $9 \div 3 = 3$. Bring down 6: $6 \div 3 = 2$. Combine results: $30 + 2 = 32$

$$\begin{array}{r} 32 \\ 3\enclose{longdiv}{96} \\ \underline{-9}\phantom{6} \\ 6 \\ \underline{-6} \\ 0 \end{array}$$

Answer:

③ $72 \div 4 = 18$
④ $96 \div 3 = 32$
