The(adsbygoogle = window.adsbygoogle || []).push({}); Dfield due to a point charge(Q) has a divergence zero

D= (Q/(4*pi*r^{2})) a_{r}(a_{r}--- unit vector)

if we calculate the divergence we get zero.

but guass law says that the divergence is a finite value not zero because a charge is present in there.

is it that in calculating divergence we also take a particular surface?

where im wrong? im confused of divergence..i tried wikipedia but could understand it upto my extent..i think somebody could help me
