What is 81 Divided by 3?
Dividing numbers is a fundamental mathematical operation that involves splitting a quantity into equal parts. In this case, we're asking how many times the number 3 fits into the number 81.
Understanding Division
Division is represented by the symbol "÷" or a forward slash "/". The number being divided is called the dividend (81 in this case), and the number we are dividing by is called the divisor (3 in this case). The result of the division is called the quotient.
Calculating 81 Divided by 3
There are a few ways to calculate this division:
1. Long Division:
This method involves writing the dividend (81) inside a division symbol and the divisor (3) outside. We then work through the division step by step, finding how many times the divisor goes into the dividend.

In this example, we see that 3 goes into 8 twice (2 x 3 = 6), leaving a remainder of 2. We then bring down the 1 from the dividend, making the number 21. 3 goes into 21 seven times (7 x 3 = 21), leaving no remainder. Therefore, 81 divided by 3 equals 27.
2. Multiplication:
We can also use multiplication to find the quotient. We know that 3 x 27 = 81. Therefore, 81 divided by 3 equals 27.
3. Calculator:
The easiest way to calculate this is by using a calculator. Simply enter 81 ÷ 3 and press the "equals" button. The calculator will display the answer, which is 27.
Conclusion
81 divided by 3 is equal to 27. This means that 81 can be divided into 27 equal groups of 3.
