Find the first occurrence of 0 (the first whole number) in the digits of e (only 35 digits in this illustration):

27182818284590452353602874713526625..., and replace it with a space:

2718281828459 452353602874713526625... Repeat the process with the next whole number, 1:

27 8281828459 452353602874713526625... Then 2:

7 8281828459 452353602874713526625... Then 3:

7 8281828459 452 53602874713526625... Then 4,5,6,7, etc., until the first occurrence of every counting number is eliminated from the digits of e.

28 2 02 5 6 ... Then consolidate gaps between the remaining digits into a single comma:

28,2,2,5,6,9,24,9,9,57,9,6,6,3,5,2,... to produce the first terms in the whole number sieve of e.
