Division Algorithm

The division algorithm is a mathematical rule that shows how to express one whole number as the product of another whole number, a quotient, and a remainder. The rule is Dividend = Divisor × Quotient + Remainder, which means a number (the dividend) is divided by another (the divisor) number that gives the quotient and the remainder. This rule is also known as Euclid’s division Lemma.
 

The division algorithm for polynomials follows the same basic principle as the division algorithm for numbers. It provides a method to divide one polynomial by another, giving a quotient and a remainder. If a(y) and b(y) are polynomials with b(y) ≠ 0, there are unique polynomials b(x) and r(x) which give: a(y) = b(y) × q(y) + r(y).

a(y) = Dividend (polynomial to be divided)
b(y) = Divisor (non-zero polynomial)
q(y) = Quotient
r(y) = Remainder

Here, the degree of the remainder r(x) is less than the degree of the divisor b(x)

The division algorithm with polynomials works much like long division with numbers. It is used when both the dividend and the divisor are polynomials. Here are the steps for the procedure to divide a Polynomial by Another Polynomial: 

Step 1: Arrange both the dividend and the divisor in standard form from highest to lowest degree.

Step 2: Divide the highest degree of the dividend by the highest degree term of the divisor to get the first term of the quotient.

Step 3: Multiply the divisor by the term and subtract the result from the dividend.

Step 4: Continue dividing the leading term of the current expression by the leading term of the divisor to find the next term in the quotient. 

Step 5: Repeat the steps until you can’t divide. That remainder becomes your final remainder.
 

The division algorithm for linear divisors is a simple rule that helps to check that a polynomial is divided correctly. When dividing a higher-degree polynomial by a lower-degree polynomial, this provides the quotient and the remainder. The division algorithm proves that multiplying the divisor by the quotient and adding the remainder, we get the original polynomial.

Division Algorithm For General Divisors

The division algorithm for polynomials is a rule that helps to divide any polynomial by another.  The degree of the divisor must be less than or equal to the dividend. The degree of the remainder is always less than the divisor.
 

There is a rule in the division algorithm that helps to divide two whole numbers
Dividend = Divisor × Quotient + Remainder

While solving the division algorithm, there are several steps to take to divide two numbers. Here are the steps

• First, identify the dividend and the divisor. While determining the dividend and the divisor, remember that the divisor is always smaller than the dividend.
• Solving the problem, look at the first digit of the dividend from the left. If that part of the dividend is smaller than the divisor, include the next digit until the number is greater than or equal to the divisor. 
• Then multiply the divisor by the quotient digit, subtract the result from the selected part of the dividend to get a remainder.
• Repeat the process that gives a remainder that is smaller than the divisor.
• The process ends when the remainder is smaller than the divisor.
   

The division algorithm has practical applications in various real-world contexts beyond academics. The division algorithm helps to divide things into equal parts, calculating, etc. Here are some real-life applications given below

• 3D modeling: Division algorithms are used in 3D modeling or graphic designing to divide large tasks like shading or texture mapping into equal parts to assign to the processors.
• Robotics and Automation: The division algorithm is used to schedule tasks in robotics. Robots are performing the tasks in a loop repeatedly, using division to break the time or action into a repeatable cycle.
• Telecommunications: In telecommunication, it helps with data transmission, like sending large data into equal-sized parts. If some data is left over, it becomes a smaller packet.
• Engineering: Engineers are using the division algorithm when designing machines with gears. Engineers often use division to calculate the angular rotation or the total turns by a set ratio to find how many times a gear must rotate.  
• Physics: The division algorithm helps to divide the total time by the time of a wave to find how many complete cycles occur in wave physics.
