20 ÷ 5 = 4, because 20 apples contain five apples four times. That is an example of division as quotition rather than as partition. One can also say that 20 ÷ 5 = 4 because when 20 apples are divided into 5 equal sets of apples, then there are 4 in each such set. That is division as partition rather than as quotition.
Division is one of the four basic operations of arithmetic, the others being addition, subtraction, and multiplication.
The division of two natural numbers is the process of calculating the number of times one number is contained within another one.[1]:7
For example, in the picture on the right, the 20 apples are divided into four groups of five apples, meaning that twenty divided by five gives four, or four is the result of division of twenty by five.
This is denoted as 20 / 5 = 4, 20 ÷ 5 = 4, or 20/5 = 4
可见20/5=4的英文表示方式为: twenty divided by five gives four.
