Division by nine : Examples • • 32 by 9 =3 R 5 32 is the dividend. 9 is the divisor. 3 is the quotient and is also the first digit of the dividend. 5 is the remainder and is also the sum of the two digits of the dividend (5 = 3 +2). Prasad 321 by 9 = 35 R 6 • 3 is the first digit of the quotient and the dividend. • 5 (= 3 +2) is the second digit of the quotient and the sum of the first two digits of the dividend. • 6 (= 5 +1) is the remainder and the sum of the three digits of the dividend. Division 2

Division by nine : Boundary Condition 342 by 9 = 37 R 9 OOPS! = 38 • When remainder is equal to or greater than the divisor, it needs correction. Prasad 346 by 9 = 37 R 13 OOPS! = 38 R 4 • Moral of the Story: Use short-cuts for calculation, but be careful, because they do not work in all cases. Division 4

Division by eight : Examples Easy vs Messy 31 by 8 =3 R 7 310 by 8 = 37 R 14 = 38 R 6 • 31 is the dividend. • 8 is the divisor. • 3 is the quotient and is the first digit. • 7 is the remainder and is the sum of the twice of the first digit and the second digit (7 = 2*3 +1). Prasad • 3 is the first digit. • 7 (= 2*3 +1) is the sum of two times the first digit and the second digit. • 14 (= 2*7 +0) is the sum of two times the first two digits and the third digit. Division 9
