Why is Long Division Important?
Long division is a crucial mathematical theory that has several utilization in different domains, involving finance, engineering, and science. It is a fundamental arithmetic function which is utilized to figure out a wide array of problems, such as figuring out interest rates, measuring the length 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 figuring out intricate problems which include huge numbers and need accurate calculations.
Stages Involved in Long Division
Here are the procedures involved in long division:
Step 1: Write the dividend (the value being divided) on the left and the divisor (the value 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. Note down the quotient (the result of the division) above the digit or set of digits.
Step 3: Multiply the quotient by the divisor and write the result 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 amount remaining 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: 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.
Solution:
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
So, 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 problematic concept to conquer, and there are many ordinary mistakes that students make when working with long division. One usual error is to forget to note down the remainder when dividing. Another common mistake is to wrongly position the decimal point while dividing decimal numbers. Learners may also forget to carry over figures when subtracting the product within the dividend.
To avoid making these errors, it is important to work on long division regularly and ready carefully each step of the process. It can also be beneficial to revisit your calculations using a calculator or by performing the division in reverse to make sure that your result is correct.
Additionally, it is crucial to comprehend the fundamental principles behind long division, such as the connection among the quotient, dividend, divisor, and remainder. By mastering the essentials of long division and avoiding usual errors, individuals can improve their abilities and obtain self-esteem in their ability to solve intricate problems.
