While I'm not exactly sure what you're referring to by "supposed to divide," dividing is a mathematical operation that involves splitting a quantity or number into equal parts. Division is typically used to find the quotient or result of dividing one number (the dividend) by another number (the divisor). It can be done by using specific mathematical operations. If you have a specific question or want to know how to perform a particular division problem, please provide more details, and I'll be happy to help!
