Float straight up!
Think of Money!
$4.80 ÷ 2
Dividing decimals is just sharing dollars and dimes fairly among groups:
4 Whole Dollars
$4 ÷ 2 = $2
8 Dimes (Tenths)
80¢ ÷ 2 = 40¢
Total share = $2.40 per person

Elevator Step Raise the decimal straight up above 7.5 to get the decimal ready.
Cycle 1 (Divide Ones) 3 goes into 7 2 times.
3 × 2 = 6. Subtract: 7 − 6 = 1.
Cycle 2 (Bring Down Tenths) Bring down the 5 to make 15.
3 goes into 15 5 times. 15 − 15 = 0.
