Divide a decimal by a whole number
Rename the decimal in tenths or hundredths, divide, then rename back. 2.4 is 24 tenths, and 24 tenths ÷ 3 = 8 tenths = 0.8. If the digits run out, add a zero: 3.2 = 3.20 = 320 hundredths, and 320 ÷ 5 = 64 hundredths = 0.64. Use a 0 to hold any empty place, as in 0.36 ÷ 4 = 0.09.
