Why is Long Division Important?
Long division is an essential math theory which has several uses in various domains, involving engineering, science and finance. It is an important math operation that is utilized to solve a wide range of problems, for example, working out interest rates, measuring the length of time required to finish a project, and figuring out the length traveled by an object.
Long division is also utilized in algebra to factor polynomials and figure out equations. It is an important tool for figuring out complicated problems that include enormous numbers and requires precise calculations.
Stages 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: 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) prior the digit or set of digits.
Step 3: Multiply the quotient by the divisor and write the outcome below the digit or set of digits.
Step 4: Subtract the result obtained 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 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 processed.
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
As a result, 562 divided by 4 is 140 with a remainder of 2.
Example 2: Divide 1789 by 21.
Workings:
85
-----
21 | 1789
21
---
158
147

11
As a result, 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 numerous ordinary errors that students make when performing long division. One common mistake is to forget to write down the remainder when dividing. One more common mistake is to incorrectly place the decimal point when dividing decimal numbers. Learners might also forget to carry over values when subtracting the product within the dividend.
To avoid making these errors, it is important to practice long division regularly and be mindful of ever step of the process. It can further be helpful to check your work using a calculator or by working the division in reverse to assure that your result is right.
In addition, it is crucial to get a grasp of the rudimental principles about long division, such as the link between the dividend, divisor, quotient, and remainder. By conquering the fundamentals of long division and preventing usual errors, individuals can enhance their skills and obtain self-esteem in their ability to figure out complex problems.
