What is the value of -36 / 9?

Explication

9 fits into 36 exactly 4 times, and sharing a quantity that sits below zero into 9 equal parts leaves every part below zero as well, so the quotient keeps its minus sign. Answering 4 divides the sizes correctly but moves the result to the positive side of zero, while joining the 36 and the 9 by addition or subtraction answers a question that was never asked.
