Long division is further applied in algebra to factor polynomials and work out equations. It is a crucial tool for working out intricate problems that involve large numbers and need exact calculations.
Procedures Involved in Long Division
Here are the steps involved in long division:
Step 1: Write the dividend (the number 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. 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 result beneath 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. Note down the remainder (the value remaining after the division) below 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.
Solution:
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
Thus, 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
So, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult concept to conquer, and there are many common errors which students make when performing long division. One usual mistake is to forget to write down the remainder when dividing. Another common mistake is to incorrectly position the decimal point while dividing decimal numbers. Students might also forget to carry over figures when subtracting the product within the dividend.
To avoid making these errors, it is crucial to practice long division frequently and be mindful of ever step of the procedure. It can further be helpful to check your work utilizing a calculator or by performing the division in reverse to make sure that your answer is correct.
Additionally, it is crucial to get a grasp of the rudimental principles regarding long division, such as the link among the dividend, divisor, quotient, and remainder. By conquering the essentials of long division and avoiding common mistakes, everyone can enhance their abilities and gain confidence in their skill to solve complicated challenges.
