Long division is further utilized in algebra to factor polynomials and solve equations. It is a crucial tool for figuring out complex problems that involve large numbers 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: Calculate 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 beneath the digit or set of digits.
Step 4: Subtract the outcome 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 until all the digits in the dividend have been refined.
Examples of Long Division
Here are few examples of long division:
Example 1: Divide 562 by 4.
Solution:
140
--------
4 | 562
4
--
16
16
---
2
So, 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
So, 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
So, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a difficult theory to master, and there are many common mistakes which learners make when performing long division. One common mistake is to forget to write down the remainder when dividing. Another common error is to incorrectly put the decimal point when dividing decimal numbers. Students may further forget to carry over figures when subtracting the product within the dividend.
To avoid making these mistakes, it is important to practice long division frequently and ready carefully ever step of the process. It can further be helpful to revisit your calculations using a calculator or by working the division in reverse to assure that your result is correct.
Furthermore, it is essential to understand the rudimental principles about long division, for instance, the relationship among the dividend, divisor, quotient, and remainder. By conquering the essentials of long division and preventing usual errors, anyone can enhance their abilities and gain confidence in their skill to figure out complex problems.
