How Many Times Does 21 Go Into 51 ?

How many 21 number inside 51 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 51 is the dividend.

2 - Perform the Division

To find out how many times 21 goes into 51, we perform the division 51 ÷ 21 .

3 - Calculate

Divide 51 by 21:

51 ÷ 21 = 2.4286

However, since we are looking for how many times 21 fully goes into 51, we focus on the whole number part of the quotient.

4 - Result

21 goes into 51 exactly **2 times** with a remainder.

5 - Check the Remainder

Multiply the quotient (2) by the divisor (21):

2 × 21 = 42

Subtract this product from the original number (51):

51 - 42 = 9

So, the remainder is 9.

Conclusion

Answer: 21 goes into 51 exactly **2 times** with a remainder of 9.
Remainder: 9
