Grep for strings

Hi,

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.94 Safari/537.36

How can I grep for the strings chrome and safari from a file, and if chrome print Chrome/40.0.2214.94 to a file and also count the number of times chrome is found?

Thanks
