I'm not sure if I was right about dividing .3 in the beginning from the radical.

You didn't need to divide by 0.3. You also divided 6.3 by 0.3 as well as dividing $\sqrt{48}$ by $\sqrt{0.3}$ so in total you divided by $0.3\sqrt{0.3}$. If you want to do this you also have to multiply by $0.3\sqrt{0.3}$ to effectively multiply by 1 so that you don't change the value of it, to balance things.
Also there is no need bring everything inside the square root so that it is $\sqrt{70560}$ because you'll end up bringing it all outside the square root in the end.
$6.3\sqrt{48}= 6.3\sqrt{6\times8}=6.3\sqrt{2\times3\times2\times2 \times2}= 6.3\times 2\times 2\sqrt{3}=25.2\sqrt{3}$
