I believe the answer is:

forks

I'm a little stuck... Click here to teach me more about this clue!

'divisions' is the definition.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for forks that I've seen before include "attacks two men at same time?" , "shed tools" .)
