To insert $ globally after four characters:

$ echo "exampleexampleexampleexample" | sed 's/.{4}/&$/g'

exam$plee$xamp$leex$ampl$eexa$mple$

The . matches one character and .{4} matches four of them. The replacement part &$ consists of the matched pattern & (four characters) and $. Using the g flag, the pattern is replaced globally (every four characters).
