Formula used
Dividend = Divisor × Quotient + Remainder. The remainder keeps the dividend’s sign. Its absolute value always stays smaller than the divisor.
Decimal division continues by appending zeros after the decimal point. Fraction results reduce through the greatest common divisor. Repeating digits appear inside parentheses for clear visual recognition.

Common mistakes
Never divide by zero because no finite quotient exists. Align decimal points before shifting both values equally. Check each subtraction carefully before bringing down another digit.
Frequently asked questions
What is the dividend?
The dividend is the number being divided. It appears inside the traditional division bracket. The divisor tells how many equal groups are formed.
What is the divisor?
The divisor is the number dividing the dividend. It appears outside the division bracket. Zero cannot serve as any valid divisor in mathematics.
How is the remainder calculated?
Multiply the integer quotient by the divisor first. Subtract that product from the original dividend. The remaining amount becomes the final division remainder value.
Can decimals be divided?
Yes, decimals are converted into equivalent integer ratios. Both values shift by matching decimal places. The quotient therefore remains mathematically unchanged after equal shifting.
What is a repeating decimal?
A repeating decimal contains a recurring digit sequence. The same remainder eventually appears during division. Parentheses identify the repeating section clearly within decimal results.
Why can rounding differ?
Rounding rules handle midpoint digits in different ways. Half-even reduces repeated upward rounding bias. Truncation simply removes digits located beyond the selected precision.
Does the calculator support negative values?
Yes, either input may contain a negative sign. The quotient sign follows normal division rules. Remainders use truncation toward zero for reliable result verification.
Can very large integers be used?
Yes, exact integer arithmetic uses JavaScript BigInt values. This avoids common floating-point precision loss. Extremely long step tables may take longer to display.
