Why is Long Division Important?
Long division is a crucial math concept that has many uses in various domains, including engineering, science and finance. It is an essential mathematics operation that is applied to solve a wide array of problems, such as calculating interest rates, determining the length of time needed to finish a project, and figuring out the distance traveled by an object.
Long division is also applied in algebra to factor polynomials and solve equations. It is an essential tool for figuring out intricate challenges which consist of enormous numbers and requires precise calculations.
Stages Involved in Long Division
Here are the steps involved in long division:
Step 1: Note the dividend (the value being divided) on the left and the divisor (the value 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) above the digit or set of digits.
Step 3: Multiply the quotient by the divisor and note down the outcome below the digit or set of digits.
Step 4: Subtract the outcome achieved in step 3 from the digit or set of digits in the dividend. Note down the remainder (the value remaining after the division) below the subtraction.
Step 5: Bring down the next digit or set of digits from the dividend and append it to the remainder.
Step 6: Repeat steps 2 to 5 unless all the digits in the dividend have been refined.
Examples of Long Division
Here are handful of 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
As a result, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult idea to conquer, and there are many common mistakes that learners make when working with long division. One common error is to forget to note down the remainder when dividing. One more common mistake is to wrongly place the decimal point when dividing decimal numbers. Learners might further forget to carry over figures when subtracting the product within the dividend.
To circumvent making these mistakes, it is important to work on long division regularly and ready carefully each step of the process. It can also be beneficial to revise your calculations utilizing a calculator or by performing the division in reverse to assure that your result is correct.
Additionally, it is essential to comprehend the basic principles behind long division, for example, the relationship among the dividend, divisor, quotient, and remainder. By conquering the fundamentals of long division and preventing common errors, anyone can improve their skills and obtain self-esteem in their ability to solve complex challenges.
