"without division" means by general consent, without objection. What that means is that, if for some reason it's obvious that the entire membership agrees there should be an election, they don't have to go through the formality of voting for it. Motions (usually insignificant ones) passed "without objection" by a simple announcement from the chair are very common in the US Congress, but I'm not sure if or how often that procedure is used in Parliament.
