Understanding the Basics of Division
Defining Division
Division is a mathematical operation that involves splitting a quantity into equal parts or groups. It is the opposite of multiplication and is used to find out how many times one number can be divided by another.
For example, if you have 12 apples and you want to divide them equally among 3 people, you would use division to find out that each person would get 4 apples. The division symbol is represented by a horizontal line with dots above and below it, or a slash, and the numbers involved are placed on either side of the symbol.
Division Symbols and Terminology
The division symbol is represented by various symbols and terms. The most common symbol is a horizontal line with dots above and below it, which is read as “divided by” or “over”. For example, 12 divided by 3 can be written as 12/3 or 12 ÷ 3.
Another symbol used to represent division is the obelus, which looks like a small minus sign with a dot above and below it. The obelus is used less commonly than the horizontal line with dots.
The number being divided is called the dividend, while the number that divides it is called the divisor. The result of the division is called the quotient. For example, in the equation 12 ÷ 3 = 4, 12 is the dividend, 3 is the divisor, and 4 is the quotient.
It is important to note that division by zero is undefined and cannot be performed. Attempting to divide any number by zero will result in an error.
In summary, division is a mathematical operation used to split a quantity into equal parts or groups. It is represented by various symbols and terms, with the most common being a horizontal line with dots. The dividend is the number being divided, the divisor is the number that divides it, and the quotient is the result of the division.

To recall the number from memory, press the “MR” button.
For example, suppose you need to divide 245 by 5, and then divide the result by 3. Instead of calculating each division separately, you can store the result of the first division in memory and use it for the second division. After dividing 245 by 5, press the “M+” button to store the result (49) in memory. Then, divide the result by 3 by pressing “49 ÷ 3 =”. Finally, to obtain the final result, press “MR” to recall the number from memory and add it to the current result.
Checking Your Work
To ensure accuracy when dividing with a calculator, it is important to double-check your work. One way to do this is to perform the division in reverse. That is, multiply the quotient by the divisor and add the remainder to the product. The result should be equal to the dividend.
For example, suppose you need to divide 378 by 7. After performing the division, you obtain a quotient of 54 and a remainder of 0. To check your work, multiply the quotient (54) by the divisor (7) and add the remainder (0). The result should be equal to the dividend (378).
