Mistake

 * It can soon be discovered that the divisor must be $312$,
 * that $9$ cannot be in the quotient because $9$ times the divisor contains a repeated figure.
 * We therefore know that the quotient contains all the figures $1$ to $8$ once, and the rest is comparatively easy.

But of course his first deduction is not necessarily the case, as we have a second solution, where the divisor is $310$.
