Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Division
Division is one of the four basic arithmetic operations, representing the process of determining how many times one number is contained within another. In the expression 78.65/11, 78.65 is the dividend, and 11 is the divisor. The result, known as the quotient, indicates how many groups of 11 can be formed from 78.65.

Decimal Numbers
Decimal numbers are numbers that include a decimal point, which separates the whole number part from the fractional part. In the case of 78.65, the '78' represents the whole number, while '0.65' represents the fractional part. Understanding how to work with decimals is crucial for accurate calculations in division.

Order of Operations
The order of operations is a set of rules that dictates the sequence in which mathematical operations should be performed to ensure consistent results. While the question involves only division, it's important to remember that if multiple operations were present, one would follow the PEMDAS/BODMAS rules (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to solve the expression correctly.
