How should I design this Regulat expression to get rid of leading 0 from String?

Question

I have a Text string "00000012345608912" 
 
 regexreplaceall("0*$","00000012345608912",""), This will remove the 0 in tail.

I want result to be 12345608912, remove the first leading 0 numbers. 
 
 Thanks

As far as I know you need to use the "^" operator to indicate that you want the match to be from the beginning of the string (you currently have it set to match to the end of the string). 
 regexreplaceall("^0*","00000012345608912","")
