The  4 is in the ten thousands  place. It tells you there is 4 
sets of ten  thousand  in the thousand place.

10,000+10,000+10,000+10,000 = 40,000   
The 2 is in  the thousands place.  It tells you that there are 
2 sets of thousand in the thousands place.
1000+1000 = 2000
The 6 is in the tens place. It tells you there are 6 sets of 
tens in the tens place
10+10+10+10+10+10=60
The 5 is in the ones place. It tells you 
there are 5 ones in the ones place
1+1+1+1+1=5
300,000, 40,000 + 2000 + 300 + 60 + 5 = 342,365
