Have you ever traveled to multiple European countries while also transiting through the UK? What techniques did you use when applying for visas ?

If you are just transiting through the UK, you do not need to apply for a visa specifically. You can buy a connecting flight ticket without a visa. In addition, if you have a US visa or a Schengen visa, you do not need a visa for transit.
If you are applying for both Belgium and the UK, you can apply for a combined UK and Belgium visa. Otherwise, you should apply for a UK visa first because the required documents are fewer.
