Step 3:
: Set up the division

\frac{2}{9} \div \frac{1}{3}

Step 4:
: Rewrite as multiplication by the reciprocal

\frac{2}{9} \times \frac{3}{1}

Step 5:
: Multiply the numerators and denominators

\frac{2 \times 3}{9 \times 1}

Step 6:
: Simplify

\frac{6}{9}

Step 7:
: Reduce the fraction

\frac{6 \div 3}{9 \div 3} = \frac{2}{3}

Final Answer
