Division of the house

Division of the house is a parliamentary mechanism which calls for a rising vote, wherein the members of the house literally divide into groups indicating a vote in favor of or in opposition to a motion on the floor. This is the method used to decide motions in the Roman Senate, and the appropriate motion for a division of the house under Robert's Rules of Order is to "call for a division".
