Long division is further utilized in algebra to factor polynomials and solve equations. It is an important tool for figuring out intricate challenges which involve huge values and need exact calculations.
Steps Involved in Long Division
Here are the procedures involved in long division:
Step 1: Write 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. Write 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 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 value left over 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: Replicate 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
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
Thus, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult idea to conquer, and there are numerous common errors that learners make when working with long division. One general error is to forget to note down the remainder when dividing. Another usual error is to incorrectly position the decimal point when dividing decimal numbers. Students might also forget to carry over values while subtracting the product from the dividend.
To prevent making these errors, it is essential to work on long division regularly and ready carefully each stage of the process. It can further be beneficial to revisit your calculations using a calculator or by performing the division in reverse to assure that your solution is right.
Furthermore, it is crucial to comprehend the fundamental principles about long division, for example, the link between the dividend, divisor, quotient, and remainder. By conquering the fundamentals of long division and avoiding usual mistakes, anyone can enhance their skills and gain self-esteem in their ability to solve intricate problems.
