The divisor in long division is the number you are dividing by.
Here's a breakdown to understand how to identify the divisor, with an example from the provided video reference:
Identifying the Divisor
- Definition: The divisor is the number that divides another number (the dividend). It's what you're using to split the dividend into equal groups.
- Position: In a long division problem, the divisor is located outside the division bracket (the symbol "⟌"). It's the number to the left of the dividend.
Example from Reference
In the provided video reference, at [0:06], the example uses a 2-digit divisor.
- The long division problem being demonstrated in the video uses 14 as the divisor.
- The video explains that when dividing 15 by 14, you're asking "how many times does 14 go into 15?". This establishes 14 as the divisor.
Example:
In the problem 15 / 3 = 5
- 15 is the dividend
- 3 is the divisor
- 5 is the quotient
Practical insights:
- The divisor helps determine the number of groups you'll have when you divide a dividend.
- Understanding the divisor is crucial for setting up and performing the long division algorithm correctly.
