The early Egyptian Ahmes Papyrus (1650 B.C.) shows how to use a doubling method to divide 696 by 29. (George Joseph, The Crest of the Peacock, 2000, pp. 61-66) Double the divisor (29) until you go past the dividend (696). Find doubles of 29 that sum to 696: 232 + 464 = 696. Then sum the corresponding doubles of 1: 8 + 16 = 24. So, 696 divided by 29 is 24. a. Divide 4050 by 225 with this method. b. Divide 57 by 6 with this method. (Hint: Use doubles and halves.)
