Long division is a method for dividing large numbers by breaking the process into smaller, easier steps. It involves dividing the dividend by the divisor one digit at a time, starting from the left. At each step, you determine how many times the divisor fits into the current number, write that in the quotient, then subtract and bring down the next digit. You repeat this process until all digits have been used. It's a step-by-step way to find both the quotient and any remainder.
