Step By Step Calculation

Step 1: Understand Division Terms

  • Dividend: The number being divided (225).
  • 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 225 ÷ 21 to determine how many times 21 fits fully into 225.

Step 3: Perform the Division

225 ÷ 21=10.714285714286

  • Whole-number quotient: 10 (the number of times 21 fits completely into 225).

Step 4: Verify the Quotient

Multiply the quotient by the divisor to check:

10 x 21 = 210

Step 5: Calculate the Remainder

Subtract this product from the original dividend:

225 - 210 = 15

  • Remainder: 15 (the amount left over).

Final Answer

225 ÷ 21 = 10 R 15

  • 21 fits into 225 exactly 10 times with a remainder of 15.
