1. The problem is to divide 849 by 2 using long division. 2. The formula for division is: $$\text{Dividend} \div \text{Divisor} = \text{Quotient}$$ 3. Start dividing the first digit of the dividend by 2: - 8 divided by 2 equals 4. 4. Multiply 4 by 2 and subtract from 8: $$8 - (4 \times 2) = 8 - 8 = 0$$ 5. Bring down the next digit, 4, making the new number 4. 6. Divide 4 by 2: - 4 divided by 2 equals 2. 7. Multiply 2 by 2 and subtract from 4: $$4 - (2 \times 2) = 4 - 4 = 0$$ 8. Bring down the last digit, 9, making the new number 9. 9. Divide 9 by 2: - 9 divided by 2 equals 4 with a remainder. 10. Multiply 4 by 2 and subtract from 9: $$9 - (4 \times 2) = 9 - 8 = 1$$ 11. The quotient is 424 and the remainder is 1. 12. So, the division result is: $$849 \div 2 = 424 \text{ remainder } 1$$ Or as a mixed number: $$424 \frac{1}{2}$$ Or as a decimal: $$424.5$$
