abstract={Let be a positive integer and be the sum of the digits in basis *q* of the positive integer *n*. We prove that the quotient has a normal order one, where and are respectively, the number of distinct prime factors and the number of prime factors p of a positive integer n counted with multiplicity such that mod Moreover, we discuss sums of the form where *f* is a multiplicative function.},
