Why is Long Division Important?
Long division is an important math concept that has many uses in various domains, consisting of science, finance, engineering. It is a fundamental arithmetic function which is used to solve a broad range of challenges, for example, working out interest rates, determining the length of time needed to complete a project, and figuring out the length traveled by an object.
Long division is also applied in algebra to factor polynomials and figure out equations. It is a crucial tool for figuring out intricate problems that include huge values and need accurate calculations.
Stages 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: Calculate how many times the divisor could be divided into the first digit or set of digits of the dividend. Write the quotient (the outcome of the division) above the digit or set of digits.
Step 3: Multiply the quotient by the divisor and write the outcome beneath the digit or set of digits.
Step 4: Subtract the outcome obtained in step 3 from the digit or set of digits in the dividend. Write the remainder (the amount remaining after the division) underneath the subtraction.
Step 5: Bring down the next 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 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
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
Thus, 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
So, 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 common errors that learners make when performing long division. One general error is to forget to note down the remainder when dividing. Another common mistake is to incorrectly put the decimal point while dividing decimal numbers. Learners might also forget to carry over numbers when subtracting the product from the dividend.
To circumvent making these mistakes, it is important to work on long division frequently and ready carefully ever step of the process. It can also be helpful to check your work using a calculator or by working the division in reverse to ensure that your result is right.
In addition, it is essential to understand the fundamental principles behind long division, for instance, the relationship among the quotient, dividend, divisor, and remainder. By mastering the essentials of long division and preventing usual errors, individuals can better their skills and gather self-esteem in their ability to figure out intricate challenges.
