**1.** When dividing two numbers, for example, **n** divided by **m**, **n** is the *dividend* and **m** is the *divisor*; the answer is the *quotient*.

**2.** Find the location of all decimal points in the dividend and divisor.

**3.** If necessary, simplify the long division problem by moving the decimals of the divisor and dividend by the same number of decimal places, to the right, (or to the left) so that the decimal of the divisor is to the right of the last digit.

**4.** When doing long division, keep the numbers lined up straight from top to bottom under the tableau.

**5.** After each step, be sure the remainder for that step is less than the divisor. If it is not, there are three possible problems: the multiplication is wrong, the subtraction is wrong, or a greater quotient is needed.

**6.** In the end, the *remainder*, **r**, is added to the growing quotient as a fraction, \(r/m\)
