Why is Long Division Important?
Long division is a crucial math idea which has many utilization in various fields, involving science, finance, engineering. It is an important mathematics function that is utilized to work out a broad array of challenges, for instance, figuring out interest rates, determining the length of time required to complete a project, and determining the length traveled by an object.
Long division is also utilized in algebra to factor polynomials and figure out equations. It is an important tool for working out complex problems which involve huge values and requires precise calculations.
Procedures Involved in Long Division
Here are the steps involved in long division:
Step 1: Note 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 outcome of the division) prior the digit or set of digits.
Step 3: Multiply the quotient by the divisor and note down the result below 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 amount remaining after the division) below 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 processed.
Examples of Long Division
Here are few 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
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
As a result, 3475 divided by 83 is 41 with a remainder of 25.
Common Mistakes in Long Division
Long division can be a challenging theory to master, and there are several common errors that students make when working with long division. One general mistake is to forget to write down the remainder when dividing. Another common mistake is to incorrectly put the decimal point while dividing decimal numbers. Learners may also forget to carry over numbers when subtracting the product from the dividend.
To circumvent making these errors, it is essential to work on long division daily and ready carefully each step of the process. It can further be helpful to check your work utilizing a calculator or by performing the division in reverse to make sure that your solution is correct.
Furthermore, it is important to understand the rudimental principles regarding long division, for example, the connection among the quotient, dividend, divisor, and remainder. By mastering the basics of long division and preventing usual errors, everyone can improve their abilities and obtain confidence in their ability to figure out complicated problems.
