Why is Long Division Important?
Long division is an important math idea that has several applications in different domains, including engineering, science and finance. It is an essential arithmetic operation that is used to solve a wide spectrum of problems, for example, figuring out interest rates, determining the amount of time required to complete a project, and finding the length traveled by an object.
Long division is also used in algebra to factor polynomials and solve equations. It is an essential tool for solving intricate challenges which involve enormous values and need exact calculations.
Steps Involved in Long Division
Here are the stages involved in long division:
Step 1: Note the dividend (the number being divided) on the left and the divisor (the number dividing the dividend) on the left.
Step 2: Determine how many times the divisor can be divided into the first digit or set of digits of the dividend. Write the quotient (the result of the division) prior 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. Note down the remainder (the value left over after the division) below the subtraction.
Step 5: Carry down the following digit or set of digits from the dividend and append it to the remainder.
Step 6: Replicate steps 2 to 5 until all the digits in the dividend have been processed.
Examples of Long Division
Here are some examples of long division:
Example 1: Divide 562 by 4.
Workings:
140
--------
4 | 562
4
--
16
16
---
2
So, 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
Therefore, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult idea to master, and there are several ordinary errors that learners make when working with long division. One usual mistake is to forget to write down the remainder when dividing. Another usual mistake is to incorrectly place the decimal point while dividing decimal numbers. Learners may also forget to carry over figures while subtracting the product within the dividend.
To circumvent making these errors, it is essential to exercise long division regularly and pay close attention to ever stage of the procedure. It can also be helpful to revisit your calculations using a calculator or by performing the division in reverse to assure that your result is correct.
Furthermore, it is crucial to get a grasp of the basic principles behind long division, for instance, the relationship among the quotient, dividend, divisor, and remainder. By conquering the fundamentals of long division and avoiding usual mistakes, individuals can enhance their skills and gather confidence in their skill to work out complex problems.
Conclusion
Finally, long division is an essential mathematical idea which is essential for working out complicated challenges in several fields. It is applied in science, finance, engineering, and mathematics, making it a crucial ability for working professionals and learners alike.
