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]]
