Segment file with EGREP?

I have a text file with sections of the file divided by a string of
characters, i.e.

***********************************

How would I use egrep to segment the file for every 100th occurence of
the "***********************************" string?

Thank you in advance.

awk could do this easily, e.g. (untested):

awk '/***********************************/{c++;if (c==100){fn++;c=0}}
{print > FILENAME "." fn}' fn=0 file

Do you really need to use egrep?
