1. Let's start by stating the problem: How to divide a two-digit number by another number. 2. The general formula for division is: $$\text{Dividend} \div \text{Divisor} = \text{Quotient}$$ 3. Important rule: Division is splitting the dividend into equal parts defined by the divisor. 4. Example: Divide 84 by 7. 5. Step 1: Write the division as $$84 \div 7$$. 6. Step 2: See how many times 7 fits into 84. 7. Step 3: Calculate $$\frac{84}{7}$$. 8. Step 4: Simplify the fraction by canceling common factors: $$\frac{\cancel{7} \times 12}{\cancel{7}} = 12$$ 9. So, $$84 \div 7 = 12$$. 10. Explanation: 7 fits into 84 exactly 12 times, so the quotient is 12. This method works for any two-digit number divided by any divisor.
