Tornadoes typically develop from a powerful type of thunderstorm called a supercell. In a major tornado outbreak multiple supercells develop, usually ahead of a front, and thus form a rough line or a broad cluster that sweeps across a large region. The storms themselves are large and, from a human perspective, far apart, so while many tornadoes may be on the ground, they will typically be a few tens of miles apart.
One thing to note is that the number of tornadoes listed for an outbreak probably did not occur all at the same time. In most cases those tornado occurred over the course of a day or even several days. Sometimes news media inflate numbers by stating the number of tornado reports, which will be higher than the number of tornadoes as some tornadoes, especially long lived ones, are reported more than once.

That is difficult to determine as Bangladesh is a relatively poor country and does not have official record keeping of tornadoes.

So one might guess that Bangladesh gets about 45 tornadoes in an average year.
