1. The problem is to divide a two-digit number by a one-digit number. 2. The formula for division is $$\text{Dividend} \div \text{Divisor} = \text{Quotient}$$ where the dividend is the number being divided, the divisor is the number you divide by, and the quotient is the result. 3. Important rules: - The divisor cannot be zero. - Division can result in a whole number or a decimal. 4. Example problem: Divide 84 by 7. 5. Step 1: Identify dividend = 84, divisor = 7. 6. Step 2: Perform division: $$84 \div 7 = 12$$. 7. Step 3: The quotient is 12, which means 7 goes into 84 exactly 12 times. 8. Another example: Divide 56 by 8. 9. Step 1: Dividend = 56, divisor = 8. 10. Step 2: Perform division: $$56 \div 8 = 7$$. 11. Step 3: The quotient is 7. 12. One more example: Divide 93 by 3. 13. Step 1: Dividend = 93, divisor = 3. 14. Step 2: Perform division: $$93 \div 3 = 31$$. 15. Step 3: The quotient is 31. These examples show how to divide two-digit numbers by one-digit numbers step-by-step.
