How can I build a partition wall in room without damaging marble floor
If you don't want to damage the floor, the best way around this is to attach your bottom plate, usually a 2x4, to the floor with construction adhesive. Then add your studs and top plate. You could also just assemble all the framing on the floor and then raise the walls, using construction adhesive for the bottom plates, walls and ceiling if desired. The wall would be permanent but could be removed without damaging the floor
