Step 1: Understand Division Terms
- Dividend: The number being divided (155).
- 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 155 ÷ 21 to determine how many times 21 fits fully into 155.
Step 3: Perform the Division
155 ÷ 21=7.3809523809524
- Whole-number quotient: 7 (the number of times 21 fits completely into 155).
Step 4: Verify the Quotient
Multiply the quotient by the divisor to check:
7 x 21 = 147
Step 5: Calculate the Remainder
Subtract this product from the original dividend:
155 - 147 = 8
- Remainder: 8 (the amount left over).
Final Answer
155 ÷ 21 = 7 R 8
