I made this division chart to help my spouse practice division for 6 deck game, anyone finds it helpful can use it to aid your division ability.

Left and right are running counts
Top and bottom are remaining decks

I floor to the nearest half deck
All the integer remaining decks are omitted cause they are too easy to calculate. For example, 16/2=8, 17/3=between 5 & 6
All the running counts below 11 are omitted cause they are too easy
I don't use any index numbers above 8, so all the quotients above 8 are written as Duo, with the same background color as 8.

In the middle:
bolded numbers are integer TCs
numbers with a + sign are TCs with decimals
Quotients in the very left row go down to running count of 26, cause it's impossible to have a running count of 27 with 5.5 decks left


I try to make the division chart as little information as possible
The picture size fits perfectly on iPhone 6s
We take turn test each other all the quotient numbers on the edges to be more efficient
