First fold half, than main diagonal and then how is shown on the picture. The marked spot is in 1/3 of the paper.

In general, you can divide the paper into N+1 parts by:

1) Dividing it into N parts along the left edge
2) Making a crease from the bottom right corner to a distance 1/N up the left edge
3) Making the diagonal crease from the bottom left to the top right.
4) The point where these two creases intersect is a distance of 1/(N+1) from both the left and bottom edges.

Algebraicaly you can prove this because the creases form the lines y=x and y= (1 - x)/N. These intersect at the point {1/(N+1), 1/(N+1)}.

Theorems are nice, but how to make 1/5? Try to look in Origami for the Connoisseur...
At first fold in half, than one corner as shown. The 1/5 is at the marked point and red line.
