An ancient method of converting decimal numbers to binary form is to halve the number until 1 is reached. When halving an odd number round down to the number below (13 halved = 61/2 round down to 6). If the number is even then record a 0, if the number is odd then record a 1.
22 ................is even .......0
22 ÷ 2 = 11..is odd..........1
11 ÷ 2 = 5....is odd..........1
5 ÷ 2 = 2......is even........0
2 ÷ 2 = 1......is odd..........1
The binary equivalent of 22 is therefore 10110
