Partial transactions I am new to cryptocurrencies.

I want to transfer coins to multiple exchanges, how can I do it?
Can I split coins from one wallet into the exchanges?
Do I need a specific kind of wallet?
And when I withdraw coins from an exchange, can I withdraw only a part of my funds(and leave the rest in my exchange account)?

Just open accounts on all those exchanges and then get deposit addresses. Transfer funds howefver you like.

Yes.

You can just withdraw from wherever your coins are now to your deposit addresses at various exchanges.

As far as I know, every legitimate exchange supports withdrawals of whatever amounts you want. Typically there are minimum withdrawal amounts and some withdrawal fee to cover the transaction cost, but that's about it.
