I am developing a web application for a comapny. This application provides the users with quizzes. Now, I need to develop a powerful and meaningful dashboard to the management. The dashboard must show many statistics. They want me to design this dashboard in a such way that shows: show % participation = number of quizzes done divided by total number of quizzes on a monthly basis at department level and compare each division.

The question is: I have the following database design:

Employee Table: Username, Name, Job, DivisionID

Division Table: DivisionID, DivisionName

Quiz Table: QuizID, Title, Description

UserQuiz Table: UserQuizID, Score, DateTimeComplete, QuizID, Username

NOTE: The first attribute in each table is the primary key.

The SQL Query that I am trying to use for showing the results in the last three months is:

SELECT COUNT(DISTINCT dbo.UserQuiz.QuizID) AS [Total Number of Quizzes],  
       dbo.Divisions.DivisionName,
       DATENAME(Month, dbo.UserQuiz.DateTimeComplete) AS Month 
FROM dbo.UserQuiz INNER JOIN
      dbo.Quiz ON dbo.UserQuiz.QuizID = dbo.Quiz.QuizID
      INNER JOIN  dbo.employee ON dbo.UserQuiz.Username = dbo.employee.Username
      RIGHT OUTER JOIN  dbo.Divisions ON dbo.employee.DivisionCode = dbo.Divisions.SapCode
GROUP BY dbo.Divisions.DivisionName, 
   DATENAME(Month, dbo.UserQuiz.DateTimeComplete)

Also, I tried many queries and each time got something different from what I want. Frankly, I don’t have any idea about how to get the above requirement.

EDIT:
Here is the schema with some data:

    Try this one:

    SELECT 
    COUNT(DISTINCT dbo.employee.UserName) UserCount,
    (SELECT COUNT(*) FROM dbo.Quiz) AS [Total Number of Quizzes],  
    (SELECT COUNT(*) FROM dbo.Quiz)*COUNT(DISTINCT dbo.employee.UserName) AS [Total Number of Quizzes for All users],  
    dbo.Divisions.DivisionName,
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete) AS MONTH,
    COUNT(DISTINCT dbo.UserQuiz.QuizId)*COUNT(DISTINCT dbo.employee.UserName) AS [Completed This Month],
    COUNT(DISTINCT dbo.UserQuiz.QuizId)*100/(SELECT COUNT(*) FROM dbo.Quiz) AS [Percent Completion]
FROM dbo.employee
JOIN  dbo.Divisions ON dbo.employee.DivisionCode = dbo.Divisions.SapCode
LEFT JOIN dbo.UserQuiz ON dbo.UserQuiz.Username = dbo.employee.Username 
WHERE dbo.UserQuiz.DateTimeComplete IS NOT NULL
GROUP BY 
    dbo.Divisions.DivisionName, 
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete)

    just the percent completion for each division in the last month only?

    SELECT 
    dbo.Divisions.DivisionName,
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete) AS MONTH,
    COUNT(DISTINCT dbo.UserQuiz.QuizId)*COUNT(DISTINCT dbo.employee.UserName)*100/((SELECT COUNT(*) FROM dbo.Quiz)*COUNT(DISTINCT dbo.employee.UserName)) AS [Percent Completion]
FROM dbo.employee
JOIN  dbo.Divisions ON dbo.employee.DivisionCode = dbo.Divisions.SapCode
LEFT JOIN dbo.UserQuiz ON dbo.UserQuiz.Username = dbo.employee.Username 
WHERE 
    dbo.UserQuiz.DateTimeComplete IS NOT NULL
AND DATEPART(MONTH, dbo.UserQuiz.DateTimeComplete) = 12
GROUP BY 
    dbo.Divisions.DivisionName, 
    DATENAME(Month, dbo.UserQuiz.DateTimeComplete)
