What is the selling price of a dining room set at Macy's? Assume actual cost is $800 and 52% markup on selling price.

I know the answer to this is $1,666.67

The thing I am having trouble understanding is what the percentages are going towards with the total sale. I understand that we have a 52% markup on selling price which means just that, but when solving the problem: $800/(1-.52) the bottom will be the 48% which I do not know what it goes towards. Sorry if this question is worded bad and confusing I just didnt know any other way to ask it. Thanks.
