Step By Step Calculation
Step 1: Understand Division Terms
- Dividend: The number being divided (243).
- 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 243 ÷ 21 to determine how many times 21 fits fully into 243.
Step 3: Perform the Division
243 ÷ 21=11.571428571429
- Whole-number quotient: 11 (the number of times 21 fits completely into 243).
Step 4: Verify the Quotient
Multiply the quotient by the divisor to check:
11 x 21 = 231
Step 5: Calculate the Remainder
Subtract this product from the original dividend:
243 - 231 = 12
- Remainder: 12 (the amount left over).
Final Answer
243 ÷ 21 = 11 R 12
- 21 fits into 243 exactly 11 times with a remainder of 12.
