How to slash the number zero

I want to know how to get a slashed zero by using the iMac Standard wired keyboard.

I have found out how to get a slashed capital letter O which looks like this: Ø
This is done by pressing option key plus Shift plus letter o

But I want to overlay the following two characters: 0 and /
Is there a combination of keys that will give me a slash through the number 0 ?

Thanks,
