String Splitting

Hello, I'm looking into string manipulation and I'd like to split a string. Only problem is I'm not sure how to go about this. The string will contain data and within that there will be "Total:" followed by unknown data of an unknown length (although not too long). What I'd like to do is split the main string and then take out everything after "Total:" and put that into a new string variable. How could I do this?

Thanks in advance.
