Modern Puzzles by Henry Ernest Dudeney: $74$
- Queer Division
- The following is a rather curious puzzle in which we are restricted to the use of only $2$ digits.
- Find the smallest number which when divided successively by $45$, $454$, $4545$, and $45454$
- leaves the remainders $4$, $45$, $454$, and $4545$ respectively.
- This is perhaps not very easy but it affords a good arithmetical exercise.
