3. Long Division Flashcards
Define “Dividend”
- The number that is being divided into groups
Where is the dividend located?
- The top number in a fraction
- The inside number of the division bar
- The first number when written linearly
What is a divisor?
- A number that divides another number
Where is the divisor located?
- On the bottom of a fraction
- Outside the division bar
- The second number when written linearly
Define “Quotient”
- The quantity we obtain by dividing the dividend by the divisor
Define “Remainder”
- What remains after a division problem is finished
Is the remainder always greater than or less than the divisor?
- Less than
What is the 1st step in long division?
- Write the problem with a division bar
What is the 2nd step in long division?
- Determine how many times the divisor goes into the first digit of the dividend and that number above the division bar
What is the 3rd step in long division?
- Multiply the divisor by the number above the bar, and write that number below the first digit of the dividend
What is the 4th step in long division?
- Subtract the first digit of the dividend, by the number written below and write that under a line below that.
What is the 5th step in long division?
- Drop the second number of the dividend down next to the bottom number
What is the 6th step in long division?
- Determine how many times the divisor goes into the new dividend written at the bottom and continue the process as before
What is the 7th step in long divison?
- Subtract the final answer, which should be 0. The digits written above the division bar are the answer
What is the 1st common error in long division?
- Not dropping down the next digit in the dividend before proceding
What is the 2nd common error in long division?
- Not writing the divisor on the outside and the dividend on the inside
What is the 3rd common error in long division?
- Not keeping the columns lines up
How do you check your answer in long division?
- Multiply the divisor and quotient, then add the remainder
What does it mean if the remainder is larger than the divisor?
- The answer is incorrect
