Arithmetic calculators covering long division, long multiplication, order of operations (BODMAS/PEMDAS) and negative numbers. Our long division calculator shows every "bring down" step exactly as you would write it in an exam — making it invaluable for students and parents helping with homework.

Unlike calculators that show only the final answer, every Pythagorist tool displays the complete method — the same working you would write in an exam. This means you can understand the process, not just copy a number. Students who understand the method score more marks, because examiners award points for correct working even when the final answer contains an arithmetic error.

How to do long division

Divide

How many times does the divisor go into the first digit(s) of the dividend? Write the result above the dividend.

Multiply

Multiply the divisor by the number you just wrote. Write the product below the dividend digits you used.

Subtract

Subtract the product from the dividend digits above it to find the current remainder.

Bring down

Bring down the next digit of the dividend. Repeat from step 1 until there are no more digits to bring down.

Record the remainder

If a remainder exists after the last step, write it alongside the quotient (e.g. 17 ÷ 5 = 3 remainder 2), or continue dividing with decimal places.
