1. The problem is to divide 144 by 12. 2. The division formula is: $$\text{Dividend} \div \text{Divisor} = \text{Quotient}$$ 3. Substitute the values: $$144 \div 12 = ?$$ 4. To simplify, we can write it as a fraction: $$\frac{144}{12}$$ 5. Cancel common factors between numerator and denominator: $$\frac{\cancel{12} \times 12}{\cancel{12}} = 12$$ 6. Therefore, the quotient is 12. Answer: $$144 \div 12 = 12$$
