title: Find Position of Nth place within numpy array?
body: <p>Given an nth place in a 2D static numpy array, how should I calculate that point's position within said array? For an example, given the number 5 representing an nth place, and an array shape of (4, 2), I want to receive the position in the array where that nth place is located, which is position (0, 1). 5th place in an array shape of 10, 1 corresponds to position (5, 0) and so on.</p>
  
  <p>Is there a numpy function that I can use?</p>
