Regex: Matching outer substring

I haven't been able to find an example of this. Given a string that contains a substring, I want to select just the outer string.

Example:

NumberLong("98237234234")

I want to select NumberLong("") and not the number inside the quotes. This way, I can do a find and replace inside IntelliJ to get rid of that and keep the number inside.

My current regex selects the whole thing:

(NumberLong\(")\d*("\))
