$\frac{25^{\frac{2}{3}} \div 25^{\frac{1}{6}}}{\left(\frac{1}{5}\right)^{\frac{7}{6}} \div \left(\frac{1}{5}\right)^{\frac{1}{6}}}$

= $\frac{25^{\frac{2}{3} - \frac{1}{6}}}{\left(\frac{1}{5}\right)^{\frac{7}{6} - \frac{1}{6}}}$

= $\frac{25^{\frac{1}{2}}}{\frac{1}{5}}$

= $5 \div \frac{1}{5}$

= 25
