Hi Rupesh,
You can solve this with the flag pole method by making 3 in 13 the flag and 1 in 13 the pole. Please check the video on flag pole method.
Let me know if you have trouble applying it.
I am working on a couple of new mental math techniques and one of those new techniques is for division. It will take me a few weeks to make the videos and you will receive an email when I update the course with the same. When that is ready you will have an alternative to the flag pole method for division.
Thank You
Warm Regards,
Abhishek
