To solve \(\frac{4}{5}\) divided by \(\frac{1}{3}\), we can multiply by the reciprocal of the second fraction.
This means we need to calculate:
\[ \frac{4}{5} \div \frac{1}{3} = \frac{4}{5} \times \frac{3}{1} \]
Now, multiplying the fractions:
\[ \frac{4 \times 3}{5 \times 1} = \frac{12}{5} \]
Thus, \(\frac{4}{5} \div \frac{1}{3} = \frac{12}{5}\).
In mixed number form, \(\frac{12}{5}\) is equal to \(2\) and \(\frac{2}{5}\).
So, the final answer is:
\[ 2 \frac{2}{5} \]
