What is the remainder when dividing 19 by 5?

• A. 3
• B. 1
• C. 0
• D. 4

Answer: (D)

When you divide a number by a smaller number, you see how many times the divisor fits into the dividend and what’s left over. For 19 divided by 5, 5 fits into 19 three times (5 × 3 = 15), leaving 4. That leftover is the remainder. So the remainder is 4. A remainder of 3 would correspond to 5 × 3 + 3 = 18, a remainder of 1 would correspond to 16, and a remainder of 0 would mean 19 is divisible by 5, which isn’t the case.
