500-07275 500-7275 500-A46846 500-G036872 500-AW8222589 500-1528131711

500-1000 500-A44431 500-G030457 500-AB8788448 500-1770594749

Wanted the output as

Tried using derived column 

SUBSTRING(OTHER_NUMBERS_COL,1,(FINDSTRING(OTHER_NUMBERS_COL," ",1)) - 1)

SUBSTRING(OTHER_NUMBERS_COL,(FINDSTRING(OTHER_NUMBERS_COL," ",1) + 1),(FINDSTRING(OTHER_NUMBERS_COL," ",2)) - (FINDSTRING(OTHER_NUMBERS_COL," ",1) + 1)).

I would really appericate if some body could help me out with this :)
