Formula
quotient = floor(dividend / divisor), remainder = dividend - divisor × quotient
Where:
- dividend=Dividend
- divisor=Divisor
Worked Examples
Positive numbers
Find floor division of 17 by 5.
- 1Compute 17/5 = 3.4
- 2Take floor: quotient = 3
- 3Remainder = 17 - 5×3 = 2
Negative dividend
Find floor division of -17 by 5.
- 1Compute -17/5 = -3.4
- 2Floor gives quotient = -4
- 3Remainder = -17 - 5×(-4) = 3
Negative divisor
Find floor division of 17 by -5.
- 1Compute 17/(-5) = -3.4
- 2Floor gives quotient = -4
- 3Remainder = 17 - (-5×-4) = -3
Introduction
Floor division returns the greatest integer less than or equal to a quotient, plus a remainder that reconstructs the original dividend.
Formula and Method
Floor Division Calculator applies quotient = floor(dividend / divisor), remainder = dividend - divisor × quotient and returns deterministic outputs from validated inputs.
Validate each required input
Apply the stated formula
Round numeric outputs where needed
Return safe defaults when validation fails
Input Fields
Use these keys exactly as defined in calculation.ts.
- 1
dividend: Dividend
- 2
divisor: Divisor
Output Fields
These values map directly to calculation.ts return keys.
- 1
quotient: Floor-divided integer quotient
- 2
remainder: Remainder satisfying dividend = divisor×quotient + remainder
Validation Rules
Divisor must be non-zero and both inputs must be finite numbers.
Finite numeric values are required
Domain restrictions are enforced before solving
Invalid input returns default-safe outputs
Check examples to confirm expected behavior

Practical Uses
This calculator is useful for study, verification, and fast applied math checks.
Programming integer arithmetic
Number theory exercises
Algorithm design with modular logic
Checking language-specific division behavior
FAQs
What does the Floor Division Calculator compute?
It computes Quotient and supporting outputs from your inputs.
Which inputs are required?
Required inputs are: Dividend, Divisor.
How are invalid inputs handled?
When validation fails, the calculator returns safe default values and does not attempt invalid math.
Are results rounded?
Yes. Numeric outputs are rounded inside calculation.ts (typically to 6 decimal places).
Can I use negative or decimal values?
Yes. The calculator supports negatives and decimals, but divisor cannot be zero.
How should I verify my answer?
Use the worked examples and compare each output key with your manual steps.
