7. Convert the product $0.243 \times 0.325233$ to a decimal, the digit at the 2013th position after the decimal point is


$$
\begin{array}{l}
0 . \dot{2} 4 \dot{3}=\frac{243}{999}=\frac{9}{37}, 0.3 \dot{2} 523 \dot{3}=\frac{325233-3}{999990}=\frac{10841}{33333} \\
0 . \dot{2} 4 \dot{3} \times 0.3 \dot{2} 523 \dot{3}=\frac{9}{37} \times \frac{10841}{33333}=\frac{897}{11111}=0 . \dot{0} 791 \dot{1} \\
2013 \div 5=402 \cdots 3, \text{ so the digit at the } 2013 \text{th position is } 9 \text{. }
\end{array}
