Fractions and roots

I have this problem:

$\frac{\sqrt{18}+\sqrt{98}+\sqrt{50}+4}{2\sqrt{2}}$

I'm able to get to this part by myself:

$\frac{15\sqrt{2}+2}{2\sqrt{2}}$

But that's when I get stuck. The book says that the next step is:

$\frac{15\sqrt{2}}{2\sqrt{2}}+\frac{2}{2\sqrt{2}}$

But I don't understand why you can take the 2 out of the original fraction, make it the numerator of its own fraction and having root of 2 as the denominator of said fraction.
