You can use this useful routine that was posted to this newsgroup a while
ago (by Theodore Gray):

ShowStatus[status_] := LinkWrite[$ParentLink,
SetNotebookStatusLine[FrontEnd`EvaluationNotebook[], ToString[status]]]

Here is an example of how to use it:

Table[If[Mod[i, 10] == 0, ShowStatus[i]]; {i, Zeta[i]},  {i, 500}];
