EXAMPLE

As a word, A003849 = 01001010010010100..., and replacing each 00 by 2 gives 012101212101210...

MATHEMATICA

s = Nest[Flatten[# /. {0 -> {0, 1}, 1 -> {0}}] &, {0}, 13]  (* A003849 *)

w = StringJoin[Map[ToString, s]]

w1 = StringReplace[w, {"00" -> "2"}]

st = ToCharacterCode[w1] - 48 (* A284620 *)

Flatten[Position[st, 0]]  (* A284621 *)

Flatten[Position[st, 1]]  (* A005843 *)

Flatten[Position[st, 2]]  (* A130568 *)
