The design of the Through command is not very convenient. The Presentations
Application has the additional PushOnto command.

<< Presentations`

Divide[f1, f2][x] // PushOnto[{f1, f2}]

f1[x]/f2[x]

Through[Divide[f1, f2][x]]
f1[x] (1/f2)[x]

(* When what I want is: Divide[f1[x],f2[x]] . An uncomfortable consequence
of the way Mathematica treats division.*)

Divide[f1, f2] // FullForm
Times[f1, Power[f2, -1]]
