1/7=0.142857142857...
2/7= 0.285714285714...
3/7= 0.428571428571...
4/7= 0.571428571428...
and so on.
what's also remarkable is that the digits missing (discounting trivial left-side place holders) are: 0,3,6, and 9. I always knew these digits were missing but didn't think much of it until dreaming about it...these excluded are multiples of 3. hmmmm!
