Since multiplication and division are inverse operations, if 6 × 4 = 24, then 24 ÷ 4 = 6 and 24 ÷ 6 = 4. Division answers the question: "How many groups of 4 are in 24?"

The dividend is the number being divided (45). The divisor is the number you divide by (9). The quotient is the result (5). Remember: "Dividend ÷ Divisor = Quotient".

29 ÷ 4 = 7 with remainder 1 (since 4 × 7 = 28, and 29 - 28 = 1). Each friend gets 7 cookies, and 1 cookie remains.

Division by zero is undefined in mathematics. There is no number that multiplied by 0 equals 12 (since anything × 0 = 0). You cannot divide by zero.

Zero divided by any non-zero number equals 0. If you have nothing and split it into 15 groups, each group still has nothing.

The fact family for 7, 8, 56 includes: 7 × 8 = 56, 8 × 7 = 56, 56 ÷ 7 = 8, and 56 ÷ 8 = 7. Both division facts are correct.

The steps: Divide (5 into 17 goes 3), Multiply (3 × 5 = 15), Subtract (17 - 15 = 2), Bring down (bring down the 5 to make 25), then Repeat. Multiply comes right after dividing.

Divisibility by 3: sum the digits; if the sum is divisible by 3, the original number is divisible by 3. Example: 27 → 2 + 7 = 9, and 9 ÷ 3 = 3, so 27 is divisible by 3.

420 ÷ 7 = 60 (since 42 ÷ 7 = 6, then add the zero). 420 is close to 412 and divides evenly by 7. The actual quotient is about 58.85, so 60 is a reasonable estimate.

250 ÷ 8 = 31 remainder 2 (since 8 × 31 = 248, and 250 - 248 = 2). You can pack 31 full boxes, and 2 pencils remain.
