Dividing 1 by 998001 gives every three digit number from 001 to 999 in order. Dividing 1 by 9801 will give every two digit number from 01 to 99 in order. Ooooooor you can type in 5318008 and show it to everyone upside down and we'll all have a laugh about it in Algebra before going back to playing drug dealer on our TI-82s (I went to high school in the 90's, kids -- we didn't have T-1000's or whatever the hell they're up to now).
