Find $(1421 \div 7 + 47) \div 50 \cdot 9.$
Recall that we should work within the parentheses first. \[1421 \div 7 + 47 = (1421 \div 7) + 47 = 203 + 47 = 250.\] Then, we should calculate the multiplication and division from left to right. \begin{align*}250 \div 50 \cdot 9 &= (250 \div 50) \cdot 9\\ &= 5 \cdot 9 = \boxed{45}.\end{align*}
