Knit 5, then bind off the next 4 stitches, then knit 29, then bind off the next 4 stitches, then knit across.
Knit 5. Knit 2, bind off as normal, count the stitch you passed over as 1, count a total of 4 stitches the same way, the loop on you needle counts as 1 of 29, for the next BO knit 2, count 4 passed stitches as before, you should have 1 loop on you needle and 28 remaining to knit.
You can place a marker after the first 5, then after 4, 29, 4 stitches to help you see where your bind off begins and ends. I have a hard time with this too, I'm not one of the wise ones, but have found ways to get the count to come out right. HTH but if not, someone will come to your rescue.
I should never overestimate my basic arithmetic skills.
