Another interesting feature of dividing by 7 is that the decimal repeats as: 0.142857 = 1/7 0.285714 = 2/7 0.428571 = 3/7 0.571428 = 4/7 0.714285 = 5/7 0.85714

Another interesting feature of dividing by 7 is that the decimal repeats as: 0.142857 = 1/7 0.285714 = 2/7 0.428571 = 3/7 0.571428 = 4/7 0.714285 = 5/7 0.857142 = 6/7 you can see the first digit after the decimal point increases in numerical order through the available numbers in the pattern, the proceeds to repeat in the same order Some other prime denominators behave the same way. For example, 1/17th is 0.0588235294117647 and the first digit after the decimal point increases like 0,1,1,2,2,3,4,4,5,5,6,7,7,8,8,9 ... Where there are 2 of the same number in the sequence, the first time you encounter that number you start from it's first ocurrence so for example 3/17 is 0.2941176470588235 This makes for a pretty spooky party trick but I can tell you from experience it doesn't attract the opposite sex.
