1. State the problem: Compute $5890 \div 10$. 1. Work: Express the division and simplify. Compute $5890 = 10 \times 589 + 0$. Therefore $5890 \div 10 = 589$. Final answer: $5890 \div 10 = 589$. 2. State the problem: Compute $6312 \div 12$. 2. Work: Recognize multiples of 12 and divide. Compute $12 \times 526 = 6312$. Therefore $6312 \div 12 = 526$. Final answer: $6312 \div 12 = 526$. 3. State the problem: Compute $5528 \div 9$. 3. Work: Divide to find quotient and remainder. Compute $9 \times 614 = 5526$ and remainder $5528 - 5526 = 2$. So $5528 \div 9 = 614 \frac{2}{9}$. As a decimal this is $614.\overline{2}$. Final answer: $5528 \div 9 = 614 \frac{2}{9} = 614.\overline{2}$.
