Integer division is division in which the fractional part (remainder) is discarded is called integer division and is sometimes denoted \. Integer division can be defined as a\b congruent ⌊a/b⌋, where "/" denotes normal division and ⌊x⌋ is the floor function. For example, 10/3 = 3 + 1/3, so 10\3 = 3. Integer division is implemented in the Wolfram Language as Quotient[a, b].
