Blow up the origin and use the chart $x=uy$, giving the <strict transform> $u^2-y^3=0$. Blow up its remaining singular point and use $u=vy$, giving $v^2-y=0$, which is smooth because its derivative in $y$ is $-1$. The complementary chart at each stage has no point of the <strict transform> on its exceptional divisor. These two <blowups of a smooth algebraic surface> resolve the branch, although the smooth transform is still tangent to an exceptional divisor.
