I can make a rectangle and divide that rectangle into two parts. One part I can label 80 and the other part I can label 4 to show a total of 84. On one side of the rectangle I label 4 for the divisor. I can find the quotient by finding the quotient in each part of the rectangle. 84 ÷ 4 = 20. 4 ÷ 4 = 1. The quotient is 20 + 1 = 21.
