The motivation for this article grew out of a problem presented to me by an artist colleague at Augustana University College, Keith Harder. He had located the thirds, fourths, fifths and so on of the diagonals of a rectangle on a grid by methods in harmony with those described here and was looking for a mathematical justification of the methods. The grid illustrated a variety of methods of finding these thirds, fourths, fifths and so on. In the interests of simplicity, I have focused on just one.
