A recipe calls for \( \frac{3}{4} \) cup of sugar for every \( \frac{1}{2} \) cup of butter. If you want to make a larger batch and use 2 cups of butter, how many cups of sugar do you need? Also, if you only have a 1/3 cup measuring cup, how many times will you need to fill it to get the required amount of sugar? Let's think step by step and output the final answer within \boxed{}.
