How to Solve 82/3 Without A Calculator

Reviewed by Calculator Editorial Team

Dividing numbers without a calculator can be done using simple long division methods. This guide will walk you through solving 82 divided by 3 step-by-step, including how to handle remainders and express the result as a decimal or mixed number.

Step-by-Step Method for Solving 82/3

To divide 82 by 3 without a calculator, follow these steps:

  1. Set Up the Division

    Write the dividend (82) and divisor (3) in the long division format:

       3 ) 82
                     ________

  2. Divide the First Digit

    Divide the first digit of the dividend (8) by the divisor (3). Since 3 doesn't go into 8, we consider the first two digits (82).

    3 × 27 = 81 (the largest multiple of 3 that's less than or equal to 82)

  3. Multiply and Subtract

    Multiply the divisor (3) by the quotient digit (27) and write the result under the dividend.

       3 ) 82
                     - 81
                     ________
                        1

    Subtract 81 from 82 to get the remainder (1).

  4. Bring Down and Add Decimal

    Since there are no more digits to bring down, we add a decimal point and a zero to the dividend, making it 1.0.

       3 ) 82.0
                     - 81
                     ________
                        1.0

  5. Continue Division

    Now divide 10 by 3. 3 × 3 = 9, which is the largest multiple of 3 that fits into 10.

       3 ) 82.0
                     - 81
                     ________
                        1.0
                        - 9
                        _____
                         1

    Subtract 9 from 10 to get the new remainder (1).

  6. Final Result

    The division process continues indefinitely, resulting in a repeating decimal. The exact value is 27.333... (27 with the digit 3 repeating).

Worked Example

Let's solve 82/3 using the long division method:

   3 ) 82.000...
                     - 81
                     ________
                        1.000...
                        - 9
                        _____
                         1.000...
                        - 9
                        _____
                         1.000...
                        - 9
                        _____
                         1.000...

The result is 27.333..., which can be expressed as 27 1/3 or 27.333... (repeating).

Formula Explained

The division formula is:

Dividend ÷ Divisor = Quotient

82 ÷ 3 = 27.333...

Where:

  • Dividend - The number being divided (82)
  • Divisor - The number dividing the dividend (3)
  • Quotient - The result of the division (27.333...)

Note: When the division doesn't result in a whole number, the quotient can be expressed as a decimal or mixed number.
