Puzzletime

 Here’s a puzzle I’ve lifted from THIS blog (who got it from Facebook poster Millie Johnson):


Arrange the digits 0‑9 into a ten-digit number such that the leftmost n digits comprise a number divisible by n. For example, if the number is ABCDEFGHJK, the three-digit number ABC must be divisible by 3, the five-digit number ABCDE must be divisible by 5, and so on.
