Understanding the Problem

When we are given a division problem like $$3,723 \div 51$$, we need to find the quotient, which is the result of the division operation. To complete the model, we need to perform the division and represent the result in the correct format.

Breaking Down the Problem

To solve this problem, we can use the concept of long division. We will divide the dividend (3,723) by the divisor (51) and find the quotient.

Step 1: Divide the First Digit

We start by dividing the first digit of the dividend (3) by the divisor (51). Since 3 is less than 51, we can't divide it directly. We need to add a zero to the dividend to make it a two-digit number.

Step 2: Divide the Two-Digit Number

Now, we divide the two-digit number (30) by the divisor (51). We can see that 30 is less than 51, so we need to add another zero to the dividend.

Step 3: Continue Dividing

We continue dividing the dividend by the divisor, adding zeros as needed, until we reach the end of the dividend.

Step 4: Find the Quotient

After performing the division, we find that the quotient is 73.

Representing the Result

To represent the result in the correct format, we need to write the quotient (73) in the box.

Conclusion

In conclusion, to complete the model to represent $$3,723 \div 51$$, we need to perform the division and find the quotient. We can use the concept of long division to solve this problem. By following the steps outlined above, we can find the correct quotient and represent the result in the correct format.

Example

Let's consider an example to illustrate this concept. Suppose we want to find the quotient of $$4,321 \div 67$$. We can use the same steps outlined above to find the quotient.

Step 1: Divide the First Digit

We start by dividing the first digit of the dividend (4) by the divisor (67). Since 4 is less than 67, we can't divide it directly. We need to add a zero to the dividend to make it a two-digit number.

Step 2: Divide the Two-Digit Number

Now, we divide the two-digit number (40) by the divisor (67). We can see that 40 is less than 67, so we need to add another zero to the dividend.

Step 3: Continue Dividing

We continue dividing the dividend by the divisor, adding zeros as needed, until we reach the end of the dividend.

Step 4: Find the Quotient

After performing the division, we find that the quotient is 64.

Representing the Result

To represent the result in the correct format, we need to write the quotient (64) in the box.

Importance of Division

Division is an essential mathematical operation that helps us to find the quotient of a given dividend and divisor. It has numerous applications in real-life situations, such as sharing, grouping, and measuring.

Real-Life Applications

Division has many real-life applications, such as:

Sharing: When we want to share a certain number of items among a group of people, we need to divide the items among them.
Grouping: When we want to group a certain number of items into smaller groups, we need to divide the items into groups.
Measuring: When we want to measure a certain quantity, we need to divide it into smaller units.

Conclusion

In conclusion, division is an essential mathematical operation that helps us to find the quotient of a given dividend and divisor. It has numerous applications in real-life situations, such as sharing, grouping, and measuring. By understanding the concept of division, we can solve problems and make informed decisions in our daily lives.
