Why is Long Division Important?
Long division is an essential math idea that has several applications in various fields, consisting of engineering, science and finance. It is an important math operation which is used to figure out a broad spectrum of challenges, such as figuring out interest rates, determining the amount of time required to complete a project, and figuring out the length traveled by an object.
Long division is further used in algebra to factor polynomials and figure out equations. It is an essential tool for solving complicated challenges which consist of huge numbers and need precise calculations.
Steps Involved in Long Division
Here are the stages involved in long division:
Step 1: Write the dividend (the value being divided) on the left and the divisor (the number dividing the dividend) on the left.
Step 2: Figure out how many times the divisor could be divided into the first digit or set of digits of the dividend. Write the quotient (the result of the division) above the digit or set of digits.
Step 3: Multiply the quotient by the divisor and note down the result below the digit or set of digits.
Step 4: Subtract the result achieved in step 3 from the digit or set of digits in the dividend. Write the remainder (the amount left over after the division) underneath the subtraction.
Step 5: Carry down the following digit or set of digits from the dividend and append it to the remainder.
Step 6: Repeat steps 2 to 5 until all the digits in the dividend have been refined.
Examples of Long Division
Here are few examples of long division:
Example 1: Divide 562 by 4.
Workings:
140
--------
4 | 562
4
--
16
16
---
2
Therefore, 562 divided by 4 is 140 with a remainder of 2.
Example 2: Divide 1789 by 21.
Solution:
85
-----
21 | 1789
21
---
158
147

11
Therefore, 1789 divided by 21 is 85 with a remainder of 11.
Example 3: Divide 3475 by 83.
Solution:
41
-----
83 | 3475
3326
----
149
124
---
25
Thus, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult theory to master, and there are several ordinary mistakes that students make when working with long division. One usual error is to forget to write down the remainder when dividing. Another usual mistake is to wrongly put the decimal point while dividing decimal numbers. Students may also forget to carry over figures when subtracting the product within the dividend.
To avoid making these mistakes, it is important to exercise long division regularly and ready carefully ever stage of the procedure. It can further be beneficial to check your work utilizing a calculator or by working the division in reverse to make sure that your solution is right.
Additionally, it is essential to understand the fundamental principles regarding long division, such as the relationship between the dividend, divisor, quotient, and remainder. By mastering the basics of long division and preventing usual mistakes, everyone can improve their skills and obtain confidence in their skill to work out intricate challenges.
Conclusion
Finally, long division is a crucial mathematical theory that is crucial for figuring out complex problems in several fields. It is utilized in engineering, science, finance, and mathematics, making it an important ability for working professionals and learners alike.
