What is the 2015th decimal number in the division 2015 by 7?
This is how I did it but is there an simpler way of showing this...
I did 2015/7 = 287.857142 857142 857142 857142 ...
As we have a recurring decimal for the numbers 857142, I divided 2015 by 6 which gives me a non finite answer so I then divided 2016 by 6 = 336. Therefore I concluded that the 2016th number must be an 8 and to answer the question which is 2015th number it must be the preceding number in the recurring pattern so it's 2.
Am I correct please and could anyone explain a clearer or simpler way, if it exist. Thank you :)
