You can think of the N$N$ point DFT as N$N$ points spaced in $0 - 2\pi$ range. Therefore the spacing between 2$2$ successive samples is $(2\pi)/N$. This is equal to $(2\pi\Delta F) / F_s$. Which is $\Delta F /F_s = 1/N$.
You can think of the N point DFT as N points spaced in $0 - 2\pi$ range. Therefore the spacing between 2 successive samples is $(2\pi)/N$. This is equal to $(2\pi\Delta F) / F_s$. Which is $\Delta F /F_s = 1/N$.
