What is 90 ÷ 4 = R?

90 ÷ 4 = 22 R2.

To explain, when you divide 90 by 4, you find how many times 4 fits into 90. 4 goes into 90 a total of 22 times (since 4 x 22 = 88), and then you have a remainder of 2 because 90 – 88 = 2. So, the full answer is 22 with a remainder of 2. Great job on your math practice!
