Well,consider this
To find whether a fraction is terminating or not
1.Prime factorize the denominator
2.If there is a prime factor besides 2 or 5 in the denominator,the fraction represents a recurring decimal..
As per statement 2
q=8..and it contains only prime factor 2
Hence this information is sufficient to prove that the given fraction contains only a finite number of non zero digits
