Section 1.6 Division of Whole Numbers 51 Answers 15. 71 R43 16. 205 R85 4. Dividing by a Many-Digit Divisor When the divisor has more than one digit, we still use a series of estimations to find the quotient. Dividing by a Two-Digit Number Example 6 Divide. Solution: To estimate the leading digit of the quotient, estimate the number of times 30 will go into 125. Since our estimate is 4. is too big.We cannot subtract 128 from 125. Revise the estimate in the quotient to 3. and subtract. Bring down the 9. Now estimate the number of times 30 will go into 299. Because our estimate is 9. and subtract. 39 R11 32 9 288 The remainder is 11. 321259 96 299 288 11 To check, verify that 1322 1392 11 1259. ✔ 30 9 270, 32 3 96 3 321259 96 299 32 4 128 4 321259 128 30 4 120, 321259 Dividing by a Many-Digit Number Example 7 Divide. 82,705 602 Solution: 137 R231 60282,705 602 2250 1806 4445 4214 231 and subtract. 602 1 602 Bring down the 0. and subtract. 602 3 1806 Bring down the 5. and subtract. 602 7 4214 The remainder is 231.
