Step-by-step solution

To solve the division 3412÷23412 \div 2, we will use long division:

  • Step 1: Start with the leftmost digit. Divide 3 by 2, which goes 1 time. Write 1 above the division bar. Multiply 1 by 2, subtract from 3 to get a remainder of 1.
  • Step 2: Bring down the next digit (4) to get 14. Divide 14 by 2, which is 7. Write 7 above the division bar. Multiply 7 by 2, subtract from 14 to get 0.
  • Step 3: Bring down the next digit (1) to get 1. Divide 1 by 2, which goes 0 times. Write 0 above the division bar.
  • Step 4: Bring down the final digit (2) to get 12. Divide 12 by 2, which is 6. Write 6 above the division bar. Multiply 6 by 2, which equals 12. Subtract from 12 to get 0.
  • Since all digits have been brought down and divided with a remainder of 0, the quotient is the complete result of the division.

Therefore, the final quotient is 1706\mathbf{1706}.

Final Answer

1706 1706

Key Points to Remember

Essential concepts to master this topic
  • Process: Divide each digit from left to right systematically
  • Technique: Bring down next digit when remainder exists, like 1 becomes 14
  • Check: Multiply quotient by divisor: 1706 × 2 = 3412 ✓

Common Mistakes

Avoid these frequent errors
  • Forgetting to write 0 when a digit doesn't divide evenly
    Don't skip writing 0 in the quotient when 1 ÷ 2 = 0 remainder 1! This shifts all following digits to wrong place values, giving 176 instead of 1706. Always write 0 as a placeholder to maintain correct position values.

FAQ

Everything you need to know about this question

Why do I write 0 when 1 divided by 2 doesn't go?

+

The 0 is a placeholder that keeps all digits in their correct positions! Without it, your answer would be 176 instead of 1706 - completely wrong because each digit shifted left.

What if I get confused about which digit to bring down next?

+

Always work left to right through the dividend (3412). After dividing 3, bring down 4. After dividing 14, bring down 1. After dividing 1, bring down 2. One digit at a time!

How do I know when I'm completely done?

+

You're done when you've brought down all digits from the dividend and have no remainder left. In this case, after dividing 12 by 2, we get 0 remainder - finished!

What does it mean to 'multiply and subtract' in each step?

+

After dividing, you multiply your quotient digit by the divisor, then subtract that from your current working number. Like: 14 ÷ 2 = 7, then 7 × 2 = 14, finally 14 - 14 = 0.

Can I check my answer a different way?

+

Yes! Multiplication is the opposite of division. Multiply your answer (1706) by the divisor (2). If you get the original number (3412), you're correct!
