1. **State the problem:** We need to divide the given dividends by their respective divisors using long division, similar to Kumon Level D. 2. **Recall the division formula:** For division, the formula is $$\text{Dividend} = (\text{Divisor} \times \text{Quotient}) + \text{Remainder}$$ where the remainder is less than the divisor. 3. **Perform each division step-by-step:** **(13) Divide 150 by 74:** - 74 goes into 150 twice (2 x 74 = 148). - Subtract 148 from 150 to get remainder 2. - So, quotient = 2, remainder = 2. **(14) Divide 236 by 74:** - 74 goes into 236 three times (3 x 74 = 222). - Subtract 222 from 236 to get remainder 14. - So, quotient = 3, remainder = 14. **(15) Divide 385 by 74:** - 74 goes into 385 five times (5 x 74 = 370). - Subtract 370 from 385 to get remainder 15. - So, quotient = 5, remainder = 15. **(16) Divide 511 by 74:** - 74 goes into 511 six times (6 x 74 = 444). - Subtract 444 from 511 to get remainder 67. - So, quotient = 6, remainder = 67. 4. **Summary of answers:** - 150 ÷ 74 = 2 remainder 2 - 236 ÷ 74 = 3 remainder 14 - 385 ÷ 74 = 5 remainder 15 - 511 ÷ 74 = 6 remainder 67 These results follow the Kumon Level D style of division with remainders.
