What I am seeing is the numbers 142857 in that order. Then for the 1/7, you grab the lowest number in that series and rotate the number until it is at front: 1

1 is the lowest, so it is 142857.
for 2/7, take the second lowest number (2), and rotate it to the front: 285714
for 3/7, third lowest (4): 428571
for 4/7 it then becomes 571428
and so on
This seems to hold up with my calculator. Pretty cool.
The 7x2, 14x2, 28x2 is jus a trick for remembering what these numbers are and their order. (142856, +1).
