For the 63/4 question i got 15.75, afterwards i multiplied 0.75 by 4 to get the remainder, wich was 3, so the last player would be starting.
The number i got before me was 25, so 25/4 = 6.25 and then drop the 6 to finde the remainder which is .25 * 4 = 1 so player 1 would be starting.
The number im going to choose is 22
