ON ADD COLUMN: DIVIDE() function with two columns yields wrong result?

Thanks for the reply.Following is my source code for dataset.Both Total and Completed are original fields and part of dataset and are grouped by node name.I am struck when trying to calculate completed/total  in power bi.

Source Code:

select ProjectId,region,state,milestonename as Nodemajormilestonename,nodemajormilestonedefaultsid,Total,completed
from (
select distinct p.WspNetworkId as projectid,p.regionid as region,p.networkstate as state,milestonename,nodemajormilestonedefaultsid,count(distinct m.projectnodeid) Total,
sum(case when actualmilestonedate is not null then 1 else 0 end) as completed
from dbo.ProjectMaster p
join
(
select
ProjectdesignId
,NodeName
,max(ProjectNodeId) ProjectNodeId
from dbo.ProjectNode
group by
ProjectDesignId
,NodeName
) n on (p.ProjectDesignId = n.ProjectDesignId)
join dbo.ProjectNodeMajorMilestone m on (n.ProjectNodeId = m.ProjectNodeId)
group by MilestoneName,p.WspNetworkId,p.regionid,p.networkstate,nodemajormilestonedefaultsid)x
order by projectid,nodemajormilestonedefaultsid

Following is my Source dataset:

Below is data tried to build in visualisation mode from datasets.here i used 

Complete = DIvide(Query1[completed],Query1[Total]  which is giving wrong results (might be data is summarized) ).For example for Preliminary Node Lock complete=2561/7701 =0.332 but is giving 37.56 which is wrong.

Thanks..
