To solve the expression \( \frac{5}{9} \div 1 \frac{2}{3} \), follow these steps:

### Step 1: Convert the mixed number to an improper fraction.
The mixed number \( 1 \frac{2}{3} \) can be converted as follows:
\[
1 \frac{2}{3} = \frac{3 \times 1 + 2}{3} = \frac{5}{3}
\]

### Step 2: Rewrite the division as multiplication by the reciprocal.
Dividing by a fraction is the same as multiplying by its reciprocal. So the expression becomes:
\[
\frac{5}{9} \div \frac{5}{3} = \frac{5}{9} \times \frac{3}{5}
\]

### Step 3: Multiply the fractions.
Multiply the numerators together and the denominators together:
\[
\frac{5 \times 3}{9 \times 5} = \frac{15}{45}
\]

### Step 4: Simplify the fraction.
\[
\frac{15}{45} = \frac{1}{3}
\]

So, \( \frac{5}{9} \div 1 \frac{2}{3} = \frac{1}{3} \).
