Step-by-step solution

To solve the problem of dividing 306 by 2 using long division, we will follow these steps:

  • Step 1: Set up the expression as 306÷2 306 \div 2 .
  • Step 2: Begin the division with the hundreds digit.
  • Step 3: Move to the tens digit and then finally to the units digit.

Let's proceed with these steps:

Step 1: Start with the hundreds place. Divide 3 (from 306) by 2. The quotient is 1, and we write it atop. Multiply 1 by 2, which gives 2, and subtract it from 3, leaving a remainder of 1. Bring down the next digit (0).

Step 2: Divide 10 by 2. The quotient is 5. Write 5 atop the division bar. Multiply 5 by 2, resulting in 10. Subtract 10 from 10, leaving no remainder. Bring down the next digit (6).

Step 3: Divide 6 by 2. The quotient is 3. Write 3 directly next to the previous quotient digits (1 and 5) on top. Multiply 3 by 2, which gives 6. Subtract this from 6, which yields 0, showing no remainder.

Thus, by performing long division, we find that:

The solution to the division 306÷2 306 \div 2 is 153\mathbf{153}.

Final Answer

153 153

Key Points to Remember

Essential concepts to master this topic
  • Setup: Place dividend inside division bar, divisor outside left
  • Technique: Divide digit by digit: 3÷2=1, bring down 0 for 10÷2=5
  • Check: Multiply quotient by divisor: 153×2=306 ✓

Common Mistakes

Avoid these frequent errors
  • Forgetting to bring down digits
    Don't divide 3÷2=1 and stop there = incomplete answer! This ignores the remaining digits and gives 1 instead of 153. Always bring down the next digit after each division step to continue the process.

FAQ

Everything you need to know about this question

What if the first digit is smaller than the divisor?

+

If 3 is smaller than your divisor, you'd combine it with the next digit. But here, 3÷2=1 works perfectly, so we can start dividing right away!

Why do I need to bring down digits one at a time?

+

Bringing down digits one at a time keeps the division organized and prevents mistakes. It's like solving the problem in manageable chunks instead of trying to do everything at once.

How do I know where to place each quotient digit?

+

Place each quotient digit directly above the dividend digit you're currently dividing. The 1 goes above the 3, the 5 above the 0, and the 3 above the 6.

What happens if there's a remainder at the end?

+

In this problem, 6÷2=3 6÷2=3 exactly with no remainder! If there was a remainder, you could continue with decimal places or express it as a fraction.

Can I check my answer without multiplying?

+

Yes! You can also add: 153+153=306 153 + 153 = 306 . Since division and multiplication are opposite operations, both methods verify your answer.
