Maybe something like:

Option Explicit
Sub testme01()

Dim wks As Worksheet
Dim newWks As Worksheet
Dim iRow As Long
Dim FirstRow As Long
Dim LastRow As Long
Dim myStep As Long

Set wks = Worksheets("Sheet1")

myStep = 50

With wks
FirstRow = 1
LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row

For iRow = FirstRow To LastRow Step myStep
Set newWks = Worksheets.Add
.Rows(iRow).Resize(myStep).Copy _
Destination:=newWks.Range("A1")
Next iRow
End With

End Sub
