The document discusses dividing decimals by whole numbers. It defines key terms like divisor, quotient, and dividend. It explains that when dividing a decimal by a whole number, the decimal point in the quotient goes above the decimal point in the dividend. An example shows dividing $9.92 by 8 cards to find the cost per card of $1.24. A second example walks through dividing 14.8 by 1.8, showing that additional zeros may need to be written in the dividend to correctly place the decimal point in the quotient.
