With the repeating decimal (recurring decimal), how can we envision how prolonged the a repeating decimal as well as the non-repeating partial have been starting to be?

Like, with 0,0142857142857 the repeating partial is 6 digits prolonged (142857) as well as the nonrepeating partial 1 series prolonged (the 0 at the back of the ,).

I usually know how to envision the repeating partial of the intermittent number.
