why would you need to divide mass by gravity?

• physics -

You multiply, not divide, mass by gravity to get weight, which is a force.
Mass is a characteristic of the material. It is the same here and on the moon or anywhere.
Weight, the force the mass exerts down on a scale, depends on the local gravitational acceleration and is for example 1/6 as large on the moon as here on earth.
