How Many Times Does 21 Go Into 81 ?

How many 21 number inside 81 number.

Step-by-Step Calculation

1 - Division Basics

Division is the process of determining how many times one number (the divisor) is contained within another number (the dividend).

In this case, 21 is the divisor, and 81 is the dividend.

2 - Perform the Division

To find out how many times 21 goes into 81, we perform the division 81 ÷ 21 .

3 - Calculate

Divide 81 by 21:

81 ÷ 21 = 3.8571

However, since we are looking for how many times 21 fully goes into 81, we focus on the whole number part of the quotient.

4 - Result

21 goes into 81 exactly **3 times** with a remainder.

5 - Check the Remainder

Multiply the quotient (3) by the divisor (21):

3 × 21 = 63

Subtract this product from the original number (81):

81 - 63 = 18

So, the remainder is 18.

Conclusion

Answer: 21 goes into 81 exactly **3 times** with a remainder of 18.
Remainder: 18
