Question

can geometric sequences be division?

Answer 1

If you mean "can we divide each term by a certain number" (as opposed to multiply each term), then yes we can

Multiplication and division are linked together

Example: Multiplying by 1/2 is the same as dividing by 2

Answer 2

Here is a geometric sequence where each term is divided by 2 to get the next term

112, 56, 28, 14, 7, ...

which is the same as multiplying each term by 1/2

eg:
112 * (1/2) = 56
