When we use the first equation with newtons second law that is F= ma, our mass in gravitation equation gets cancels out and the only quantity remains is the mass of other object which tells that acceleration does not depend on our mass but depends on the mass of earth or whatever planet we are considering.
For further explanation image is attached
Comment for any further help.
