$$18\frac{1}{6}\div\frac{7}{21}$$

$\frac{109}{2}=54.5$

Divide $\frac{18\times 6+1}{6}$ by $\frac{7}{21}$ by multiplying $\frac{18\times 6+1}{6}$ by the reciprocal of $\frac{7}{21}$.

$$\frac{\left(18\times 6+1\right)\times 21}{6\times 7}$$

Cancel out $3\times 7$ in both numerator and denominator.

$$\frac{1+6\times 18}{2}$$

Multiply $6$ and $18$ to get $108$.

$$\frac{1+108}{2}$$

Add $1$ and $108$ to get $109$.

$$\frac{109}{2}$$

$\frac{109}{2} = 54\frac{1}{2} = 54.5$
