Suppose interesting number has more than 4 digits in its decimal representation. So let it be $A = V*100000+\overline{abcde}$. So $(V*100000+\overline{abcd}) \;| \;e$ so $e=0$. Similarly $d=0$. So $A$ is not interesting. So $A$ has no more than 4 digits. Let $A=\overline{abcd}$. Obvious that $d=0$. $\overline{ab}\; |\; c*10$ and $\overline{ab}<c*10$. So max $a=4$ but by substition we can make sure that this $a$ is not working. So max $a=3$. So max $b=5$. So $c=7$. So $A=3570$.
