Split Polylines at certain increments

CCWeedcontrol

I need to create a polyline grid with vertical and horizontal lines of increments of one hundred, somehow divide each polyline/polygon by 9 and across multiple polygons/polylines and I am not sure on how go about doing it. What I have is the polygons/sections and polylines/sections lines.. The polygons/polylines are NOT evenly squared so I can't use fish net, at least I don't think...?

I was able to achieve creating the blocks with the following below but would be nice if could have populate the attributes based on a formula and this is beyond me. I attached the sections in case anyone wants to help out.

 

import arcpy, os

arcpy.env.overwriteOutput = True

def CreateFishnetsForFeats(shp, out, cell_x=0, cell_y=0, n_rows=0, n_cols=0):
    # Create file gdb to store data
    gdb = str(arcpy.CreateFileGDB_management(out, 'Fishnets.gdb').getOutput(0))

    # spatial reference
    arcpy.env.outputCoordinateSystem = arcpy.Describe(shp).spatialReference

    # Loop thru rows of input polygons
    with arcpy.da.SearchCursor(shp, ['SHAPE@', 'OID@']) as rows:
        for row in rows:
            ext = row[0].extent
            st = '%f %f' %(ext.XMin, ext.YMin)
            ort = '%f %f' %(ext.XMin, ext.YMax)

            # Create fishnet
            outFn = os.path.join(gdb, 'fish_{0}'.format(row[1]))
            arcpy.CreateFishnet_management(outFn, st, ort, cell_x,cell_y, n_rows, n_cols,
