#dcp1986: I tried with your function as below.
SELECT dbo.UF_StringSplitter('HeloEveryonehru Howslyfgoingonn HaveaGoodDayGoodMorning')
But an unexpected split occured. I think your function must be modified as below for the correct result:
IF EXISTS(SELECT * FROM sysobjects WHERE ID = OBJECT_ID('UF_StringSplitter'))
DROP FUNCTION UF_StringSplitter
GO
CREATE FUNCTION UF_StringSplitter (
#psCSString VARCHAR(MAX)
)
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #sTemp VARCHAR(MAX)
DECLARE #tTemp VARCHAR(MAX)
SET #tTemp=''
WHILE LEN(#psCSString)>15
BEGIN
SET #sTemp = LEFT(LTRIM(#psCSString), 15)
SET #psCSString = LTRIM(SUBSTRING(#psCSString,16, LEN(#psCSString)))
IF #psCSString LIKE ' %'
SET #tTemp=#tTemp+#sTemp
ELSE
SET #tTemp=#tTemp+#sTemp+' '
END
SET #tTemp=#tTemp+#psCSString
RETURN #tTemp
END

You could use a function like this
IF EXISTS(SELECT * FROM sysobjects WHERE ID = OBJECT_ID('UF_StringSplitter'))
DROP FUNCTION UF_StringSplitter
GO
CREATE FUNCTION UF_StringSplitter
(
#psCSString VARCHAR(MAX)
)
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #sTemp VARCHAR(MAX)
DECLARE #tTemp VARCHAR(MAX)
SET #tTemp=''
WHILE LEN(#psCSString)>15
BEGIN
SET #sTemp = LEFT(#psCSString, 15)
SET #psCSString = SUBSTRING(#psCSString,16, LEN(#psCSString))
IF #psCSString LIKE ' %'
SET #tTemp=#tTemp+#sTemp
ELSE
SET #tTemp=#tTemp+#sTemp+' '
END
SET #tTemp=#tTemp+#psCSString
RETURN #tTemp
END
Go
Here i have hard coded the splitting value, and you can use the function
UPDATE mytable SET mycol=dbo.UF_StringSplitter(mycol)

I don't know how to do it on a single statement, but you can create a sql function something like this
create function AddStuffCharacterInLength (#original nvarchar(100), #take int, #stuff varchar(100))
returns nvarchar(200)
AS
BEGIN
declare #result nvarchar(200)
declare #len int
declare #skip int
set #len = len(#original)
set #result = ''
set #skip = (#take * -1) + 1
while #len > 0
begin
set #result = #result + substring(#original, #skip + #take, #take)
set #len = #len - #take
set #skip = #skip + #take
if #len > 0
set #result = #result + ' '
end
RETURN #result
END
And use it like this
select dbo.AddStuffCharacterInLength ('ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ',15, ' ')
And the output should be
----------------------------------------------------------------------------------------------------
ABCDEFGHIJKLMNO PQRSTUVWXYZABCD EFGHIJKLMNOPQRS TUVWXYZ
