Moor has $2016$ white rabbit candies. He and his $n$ friends split the candies equally amongst themselves, and they find that they each have an integer number of candies. Given that $n$ is a positive integer (Moor has at least $1$ friend), how many possible values of $n$ exist?
1. We need to determine how many possible values of \( n \) exist such that Moor and his \( n \) friends can split 2016 candies equally. This means that \( n+1 \) must be a divisor of 2016.
2. First, we find the prime factorization of 2016:
   \[
   2016 = 2^5 \times 3^2 \times 7
   \]
3. The number of divisors of a number \( n = p_1^{e_1} \times p_2^{e_2} \times \cdots \times p_k^{e_k} \) is given by:
   \[
   (e_1 + 1)(e_2 + 1) \cdots (e_k + 1)
   \]
   Applying this to 2016:
   \[
   (5+1)(2+1)(1+1) = 6 \times 3 \times 2 = 36
   \]
4. These 36 divisors include 1, which corresponds to Moor having all the candies and no friends. Since Moor has at least one friend, we exclude the divisor 1.
5. Therefore, the number of possible values of \( n \) is:
   \[
   36 - 1 = 35
   \]

The final answer is \(\boxed{35}\)
