A number is divisible by 234 if:its last digit is 0, 2, 4, 6 or 8; andthe sum of its digits (the calculation repeated if required), is divisible by 9; andthe result of nine times the last digit subtracted from the number formed by the rest (the calculation repeated if required) is divisible by 13.

The quotient gives the number of times that the divisor can be subtracted from the numerator. For example, 17/5 gives a quotient of 3 [and a remainder of 3]. This is equivalent to saying that 5 can be subtracted 3 times from 17 and that will leave a remainder of 2.

The quotient of a division tell you how many times the divisor needs to be subtracted from the dividend to get a result of zero. eg 10 ÷ 2 = 5 tells you that 2 needs to be subtracted 5 times from 10 to get 0: (1) 10 - 2 = 8; (2) 8 - 2 = 6; (3) 6 - 2 = 4; (4) 4 - 2 = 2; (5) 2 - 2 = 0. With a divisor of 1, it can be subtracted exactly the same number of times as the dividend itself to get zero. With a divisor greater than 1, each subtraction removes more than 1 and so less subtractions that the dividend will be required. With a divisor less than 1 (and greater than 0) each subtraction removes less than 1; if it is subtracted the same number of times as the dividend there will be a remainder greater than zero which will require further subtractions before zero is reached. eg 3 ÷ 0.6: (1) 3 - 0.6 = 2.4; (2) 2.4 - 0.6 = 1.8; (3) 1.8 - 0.6 = 1.2 [still have 1.2 to go]; (4) 1.2 - 0.6 = 0.6; (5) 0.6 - 0.6 = 0 → 3 ÷ 0.6 = 5.

By repeated subtraction. For example 21 divided by 2 : you can take away 2 ten times and you are left with a half of two, so answer ten and a half. They probably assembled tables of divisions.
