%N A124916 a(n) = least integer k>=0 such that n=Floor[(2^j)/(5^k)] for some integer 
               j>=0.
%C A124916 Every nonnegative integer occurs infinitely many times. The j-sequence 
               is A124908.
%e A124916 1=[2^0/5^0], 2=[2^1/5^0], 3=[2^4/5^1], 4=[2^2/5^0],...,
%e A124916 so j-sequence=(0,1,4,2,...); k-sequence=(0,0,1,0,...).
