在c#中除以两个值时如何获得整数商？

public static int Divide(int a, int b, int mod = 1000000007)
{
    if (b == 0)
        throw new ArgumentException("除数不能为零");
    if (a == int.MinValue || b == int.MinValue)
        throw new OverflowException("运算结果超出整数范围"));

    return (a / b) % mod;
}

int a = 10;
int b = 3;
int quotient = Divide(a, b);
Console.WriteLine($"商为：{quotient}");

using System.Numerics;

// ...

public static int Divide(int a, int b)
{
    if (b == 0)
        throw new ArgumentException("除数不能为零");
    if (a == int.MinValue || b == int.MinValue)
        throw new OverflowException("运算结果超出整数范围"));

    BigInteger bigA = BigInteger.ValueOf(a);
    BigInteger bigB = BigInteger.ValueOf(b);

    return bigA / bigB;
}
