Match two column values from 2 data sets, then find associated values - excel

Question

The issue I'm having was hard to title, and hard to search as well.
Here's some example data.
A B C D E F
B1 04/14/16 746 B1 04/25/16 2
B1 04/15/16 180 B1 04/30/16 4
B1 04/16/16 494 B1 05/01/16 5
B1 04/17/16 726 B2 04/01/16 1
B1 04/18/16 206 B2 04/03/16 1
B1 04/19/16 22 B2 04/04/16 2
B1 04/20/16 193 B2 04/05/16 2
B1 04/21/16 739 B2 04/12/16 8
B1 04/22/16 926 B2 04/13/16 1
B1 04/23/16 748 B2 04/14/16 2
B1 04/24/16 830 B2 04/15/16 1
B1 04/25/16 272 B2 04/18/16 9
B1 04/26/16 0 B2 04/19/16 1
B1 04/27/16 0 B2 04/26/16 9
B1 04/28/16 0 B2 04/27/16 3
B1 04/29/16 0 B2 04/30/16 1
B1 04/30/16 685 B2 05/02/16 5
B1 05/01/16 770 B2 05/03/16 2
B1 05/02/16 701 B3 04/03/16 3
B1 05/03/16 181 B3 04/04/16 1
B2 04/01/16 77 B3 04/06/16 2
B2 04/02/16 182 B3 04/07/16 1
B2 04/03/16 53 B3 04/09/16 1
B2 04/04/16 32 B3 04/16/16 7
What I'm trying to do is check for matching A and D columns, as well as matching B and E columns. If the columns match I would like to take column F and divide by column C.
Also if there is no match for both A and B column values, then have return those values with a zero.
So for a match:
B1 04/25/16 =2/272
For a non-match:
B1 04/14/16 0
Thank you.

Two INDEX/MATCH Function will do it:
=IFERROR(INDEX($F$1:$F$24,MATCH(1,INDEX(($E$1:$E$24=J2)*($D$1:$D$24=I2),),0))/INDEX($C$1:$C$24,MATCH(1,INDEX(($B$1:$B$24=J2)*($A$1:$A$24=I2),),0)),0)
This is an array formula, Full column references should be avoided as the calculation are exponential and will increase the calculation times.
If a more dynamic range is wanted then use this formula:
=IFERROR(INDEX($F$1:INDEX(F:F,MATCH(1E+99,F:F)),MATCH(1,INDEX(($E$1:INDEX(E:E,MATCH(1E+99,F:F))=J2)*($D$1:INDEX(D:D,MATCH(1E+99,F:F))=I2),),0))/INDEX($C$1:INDEX(C:C,MATCH(1E+99,C:C)),MATCH(1,INDEX(($B$1:INDEX(B:B,MATCH(1E+99,C:C))=J2)*($A$1:INDEX(A:A,MATCH(1E+99,C:C))=I2),),0)),0)
This will find the last cell with data and use that to set the extents of the range. So now as the data grows or shrinks it will only look at the data and not iterate through any more or any less than what is needed to cover the entire data set.
