Why is Long Division Important?
Long division is an important mathematical theory that has several utilization in distinguished fields, including finance, engineering, and science. It is an important mathematics function that is utilized to figure out a broad spectrum of challenges, such as calculating interest rates, measuring the length of time needed to complete a project, and figuring out the distance traveled by an object.
Long division is also applied in algebra to factor polynomials and figure out equations. It is a crucial tool for working out complicated challenges which include large numbers and need precise calculations.
Stages Involved in Long Division
Here are the stages 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 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 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 following 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 some 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
So, 1789 divided by 21 is 85 with a remainder of 11.
Example 3: Divide 3475 by 83.
Workings:
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 challenging concept to master, and there are many ordinary errors which students make when working with long division. One general error is to forget to write down the remainder when dividing. Another usual error is to incorrectly position the decimal point when dividing decimal numbers. Learners may further forget to carry over numbers while subtracting the product from the dividend.
To prevent making these mistakes, it is important to practice long division regularly and ready carefully each stage of the procedure. It can further be beneficial to check your calculations using a calculator or by working the division in reverse to assure that your answer is right.
In addition, it is essential to understand the fundamental principles behind long division, such as the connection between the dividend, divisor, quotient, and remainder. By mastering the fundamentals of long division and avoiding common mistakes, anyone can improve their abilities and obtain self-esteem in their skill to solve complicated challenges.
