Hello @KathyrnSmith and welcome to the Community. Are you asking for basic multiplication/ division questions that will have no remainder? I always worked backwards. I found two 2-3- digit numbers, wrote them down so I wouldn't forget, used a calculator to find the answer, and then put the product and one of the factors into the formula.
Have you checked in the Commons to see if someone else has made an assignment or a quiz with similar questions so you could import it into your course? This is a great way to not recreate the wheel.
