Step By Step Calculation

Step 1: Understand Division Terms

  • Dividend: The number being divided (51).
  • Divisor: The number dividing the dividend (21).
  • Quotient: The whole-number result of division.
  • Remainder: The amount left over after division.

Step 2: Set Up the Division

Calculate 51 ÷ 21 to determine how many times 21 fits fully into 51.

Step 3: Perform the Division

51 ÷ 21=2.4285714285714

  • Whole-number quotient: 2 (the number of times 21 fits completely into 51).

Step 4: Verify the Quotient

Multiply the quotient by the divisor to check:

2 x 21 = 42

Step 5: Calculate the Remainder

Subtract this product from the original dividend:

51 - 42 = 9

  • Remainder: 9 (the amount left over).

Final Answer

51 ÷ 21 = 2 R 9

  • 21 fits into 51 exactly 2 times with a remainder of 9.
