Long division is further utilized in algebra to factor polynomials and work out equations. It is an important tool for working out intricate problems that include large values and need precise 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: Figure out 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) 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 achieved in step 3 from the digit or set of digits in the dividend. Write the remainder (the value 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: 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
Thus, 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 problematic concept to master, and there are several general mistakes that students make when working with long division. One usual error is to forget to write down the remainder when dividing. One more usual mistake is to incorrectly position the decimal point while dividing decimal numbers. Learners might also forget to carry over numbers while subtracting the product from the dividend.
To circumvent making these mistakes, it is essential to exercise long division frequently and pay close attention to ever step of the process. It can further be helpful to revise your calculations using a calculator or by working the division in reverse to assure that your result is right.
Additionally, it is important to understand the fundamental principles behind long division, such as the relationship between the dividend, divisor, quotient, and remainder. By conquering the fundamentals of long division and preventing usual errors, everyone can better their abilities and gather self-esteem in their ability to work out complicated challenges.
Conclusion
In conclusion, long division is a crucial mathematical theory that is essential for working out complicated challenges in many fields. It is used in science, finance, engineering, and math, making it an essential ability for working professionals and students alike.
