How to aggregate data, pass and fail as final result?

I have a list of result either having or not having Data plus has Pass and Fail like below,

var results = new List<Result>
{
    new Result{Data = new Data{Name = "A"}, Pass = 1, Fail = 0},
    new Result{Data = new Data{Name = "B"}, Pass = 3, Fail = 1},
    new Result{Pass = 1, Fail = 0}
};

I need to aggregate data and need this as final result output,

var finalResult = new FinalResult
{
    Datas = new List<Data> { new Data { Name = "A" }, new Data { Name = "B" } },
    TotalPass = 5,
    TotalFail = 1,
    Divident = 5/1
}

I tried something like below, but totalPass and totalfail, are not coming correct. Plus, how to aggregate Data?

int totalPass = 0;
int totalfail = 0;

var finalResult = new FinalResult();

foreach (var r in results)
{
    totalPass += r.Pass;
    totalfail += r.Fail;
}

finalResult.TotalFail = totalPass;
finalResult.TotalFail = totalfail;
finalResult.Divident = totalPass / totalfail;

Here are the two classes:

public class FinalResult
{
    public List<Data> Datas { get; set; }
    public int TotalPass { get; set; }
    public int TotalFail { get; set; }
    public int Divident { get; set; }
}

public class Result
{
    public Data Data { get; set; }
    public int Pass { get; set; }
    public int Fail { get; set; }
}

public class Data
{
    public string Name { get; set; }
}

var finalResult = new FinalResult
{
    Datas = results.Where(r => r.Data != null).Select(r => r.Data).ToList(),
    TotalPass = results.Sum(r => r.Pass),
    TotalFail = results.Sum(r => r.Fail)
};

// Beware of division by zero and integer division.
finalResult.Divident = finalResult.TotalPass / finalResult.TotalFail;
