Integer fractions with 7 in the denominator.

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!

1/14=0.0714285714285...

3/14=0.2142857142857...(this one has a leading 2 before the pattern starts)

parsing:
3/14=15/70=1/70+14/70=1/70+1/5=1/70+0.2

Whoah, that address doesn't have 3, 7, or 8.

If you add up the numbers you get 18. 8 - 1 = 7
