1. Set up divisor and Dividend2. Look at the Divisor, move decimal
place over to last non-zero number3. How ever many places you moved the
decimal in step 2, you move the decimal in the dividend
4. Divide as you would with a whole number
Find the quotient.5.2 ÷ 1.3
1.3 5.2 Move decimal place over once for divisor
