Example

Find the first occurrence of 0 (the first whole number) in the digits of Phi (only 35 digits in this illustration):
16180339887498948482045868343656381..., and replace it with a space:
1618 339887498948482045868343656381...  Repeat the process with the next whole number, 1:
618 339887498948482045868343656381...  Then 2:
618 33988749894848 045868343656381...  Then 3:
618  3988749894848 045868343656381...  Then 4,5,6,7, etc., until the first occurrence of every counting number is eliminated from the digits of Phi.
  1   3     9    48 04 8           ...  Then consolidate gaps between the remaining digits into a single comma:
1,3,9,48,4,8,9,9,6,5,5,0,28,70,0,  ...  to produce the first terms in the whole number sieve of Phi.
