How do you do long division?
Long division steps: 1) Divide - How many times does divisor go into the first digit(s) of dividend? 2) Multiply - Multiply quotient by divisor. 3) Subtract - Subtract result from dividend. 4) Bring down - Bring down next digit. 5) Repeat until no digits remain.

What is a remainder in division?
A remainder is what's left over when a number doesn't divide evenly. For example, 17 ÷ 5 = 3 remainder 2, because 5 × 3 = 15, and 17 - 15 = 2. Alternatively, it can be expressed as a decimal (3.4) or fraction (3 2/5).
How do you check long division answers?
To check: (Quotient × Divisor) + Remainder = Dividend. For example, if 456 ÷ 12 = 38 remainder 0, check: (38 × 12) + 0 = 456. This confirms the answer is correct.
Can you divide by zero?
No, division by zero is undefined in mathematics. You cannot divide any number by zero - it's mathematically impossible and produces an error. This calculator will show an error if you attempt to divide by zero.
