New Scientist Enigma 494 – Look Blank

by Susan Denham

From Issue 1646, 7th January 1989

In the following long division sum I’ve marked the position of each digit. I can tell you that there were no 1s and no 0s but that all other digits occurred at least twice.

Also (although you don’t actually need this information) all four digits of the answer were different.

What is the six-figure dividend?
