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.
