If data in cell A1 is
1.1.1.2 Text to parse
Cell B1 formula is
=MID(A1,1,FIND(" ",A1,1)-1)
Cell C1 formula is
=MID(A1,FIND(" ",A1,1),200)
That is assuming the space after the number is a blank space.
C1 will however return leading spaces if there is more than one space in the original text, so use TRIM
=TRIM(MID(A1,FIND(" ",A1,1),200))
Sorry, edited.
