WordPress has been removed, but content still appears online

Hello
I am rubbish with WordPress – I’ll say that upfront!

I had wordpress installed on my FTP.
I had a go with it (stupidly) using my business web address.
Google picked it up, and it now comes up on search results under my site (www.broadleydesign.co.uk).
After unsuccessfully trying to hide it, I deleted the files from my FTP. But now when I search, the content is still there.
Theres no style sheets or layout.

Why is it still there and how to I get rid of it?
I really hope you can help, I’m a graphic designer and its looks really terrible having it there.
