\begin{matrix} ? & ? & ? & ? \end{matrix} \times \begin{matrix} ? \end{matrix} = 8044 \begin{matrix} ? \end{matrix}

\frac{8044 ?}{8} > \frac{80000}{8} = 10000

\Rightarrow 8044 ? should be divisible by 9

\Rightarrow 9 ∣ 8 + 0 + 4 + 4 + ? \Rightarrow ? = 2

\Rightarrow \frac{80442}{9} \times 9 = 8938 \times 9 = 80442
