Well, the multiplication part should be easy enough. It's the long division which takes a bit more effort.

Remember, $$a ⋅ \frac{b}{c} = \frac{a ⋅ b}{c}$$

Don't tell me you've never done any arithmetic by hand.

next use long division

You could first multiply the numerator by 120 before you divide
