Explain the purpose of division to put it into context of another arithmetic operation: multiplication. Division is the inverse of multiplication. It "undoes" the operation of multiplying. For example, (60 / 20) = 3 because (20 * 3) = 60.
Identify and define the terms of a division problem. The process of division seeks to find the number of times a number called the divisor "fits into" another number called the dividend. The result of the operation is called the quotient. For example, for the equation (60 / 20) = 3, 60 is the divident, 20 is the divisor, and 3 is the quotient.
Discuss the fact that the quotient is not always a whole number because sometimes the divisor does not completely "fit" into the dividend a whole number of times. For example, for the equation (60 / 22) = 2.72, the divisor almost fits into 60 three times, but not quite. The divisor fits 2 whole times plus an additional 0.72 times. This is equivalent to saying that 22 factors into 60 twice with a remainder of (0.72 * 22) = 15.84 = 16. The discrepancy is due to the rounding of 0.72.
