實作
例外狀況
divisor
是 0 (零)。
範例
下列範例會建立 值的陣列 BigInteger 。 然後它會使用每個元素做為使用 Divide 方法的除法運算中的商數、除法運算子 (/) 和 DivRem 方法。

備註
方法 Division 會定義值的除法 BigInteger 運算。 它會啟用下列程式代碼:
BigInteger num1 = 100045632194;
BigInteger num2 = 90329434;
BigInteger quotient = num1 / num2;
let num1 = 100045632194I
let num2 = 90329434I
let quotient = num1 / num2
Dim num1 As BigInteger = 100045632194
Dim num2 As BigInteger = 90329434
Dim quotient As BigInteger = num1 / num2
不支援自定義運算子和運算元多載的語言可以改為呼叫 Divide 方法。
這個運算子的對等方法為 BigInteger.Divide(BigInteger, BigInteger)
