Why is Long Division Important?
Long division is an important math theory that has many utilization in various fields, involving finance, engineering, and science. It is an important mathematics function which is used to figure out a broad spectrum of challenges, for instance, figuring out interest rates, determining the length of time needed to complete a project, and finding the distance traveled by an object.
Long division is further utilized in algebra to factor polynomials and work out equations. It is a crucial tool for working out complicated problems which include enormous numbers and requires precise calculations.
Stages Involved in Long Division
Here are the procedures 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 can 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 note down the outcome 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. Write the remainder (the value remaining after the division) underneath the subtraction.
Step 5: Carry 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
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
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
Therefore, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a problematic idea to conquer, and there are several general mistakes which learners make when performing long division. One common error is to forget to write down the remainder when dividing. Another common error is to incorrectly position the decimal point while dividing decimal numbers. Learners might further forget to carry over numbers while subtracting the product from the dividend.
To prevent making these mistakes, it is crucial to work on long division daily and ready carefully ever step of the procedure. It can also be beneficial to check your calculations using a calculator or by working the division in reverse to ensure that your result is correct.
In addition, it is important to comprehend the fundamental principles behind long division, for instance, the connection between the dividend, divisor, quotient, and remainder. By mastering the essentials of long division and avoiding common mistakes, everyone can improve their abilities and gain self-esteem in their skill to solve complex challenges.
