Exemplos
O exemplo a seguir cria uma matriz de BigInteger valores.The following example creates an array of BigInteger values. Em seguida, ele usa cada elemento como o quociente em uma operação de divisão que usa o Divide método, o operador de divisão (/) e o DivRem método.It then uses each element as the quotient in a division operation that uses the Divide method, the division operator (/), and the DivRem method.

Comentários
Esse método preserva tanto o quociente quanto o restante que resulta da divisão de inteiros.This method preserves both the quotient and the remainder that results from integer division. Se você não estiver interessado no restante, use o Divide método ou o operador de divisão; se você estiver interessado apenas no restante, use o Remainder método.If you are not interested in the remainder, use the Divide method or the division operator; if you are only interested in the remainder, use the Remainder method.
O sinal do valor retornado remainder é o mesmo que o sinal do dividend parâmetro.The sign of the returned remainder value is the same as the sign of the dividend parameter.
O comportamento do DivRem método é idêntico ao do Math.DivRem método.The behavior of the DivRem method is identical to that of the Math.DivRem method.
