Step By Step Calculation

Step 1: Understand Division Terms

  • Dividend: The number being divided (288).
  • 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 288 ÷ 21 to determine how many times 21 fits fully into 288.

Step 3: Perform the Division

288 ÷ 21=13.714285714286

  • Whole-number quotient: 13 (the number of times 21 fits completely into 288).

Step 4: Verify the Quotient

Multiply the quotient by the divisor to check:

13 x 21 = 273

Step 5: Calculate the Remainder

Subtract this product from the original dividend:

288 - 273 = 15

  • Remainder: 15 (the amount left over).

Final Answer

288 ÷ 21 = 13 R 15

  • 21 fits into 288 exactly 13 times with a remainder of 15.
