We give various results about the distribution of the sequence {a n/n}n ≥ 1 modulo 1, where a ≥ 2 is a fixed integer. In particular, we find an explicit infinite subsequence A such that {a n/n}n∈A is uniformly distributed modulo 1. Also we show that for any constant c > 0 and a sufficiently large N, the fractional parts of the first N terms of this sequence hit every interval J ⊆ [0, 1] of length |J| ≥ c N-0.475.
