Example 3.3 FIGURE 3.5 converts 22 (dec) to binary. The number 22 divided by 2 is 11 with a remainder of 0, which is written in the right column. Then, 11 divided by 2 is 5, with a remainder of 1. Continuing until the number gets down to 0 produces a column of remainders, which, when read from the bottom up, form the binary number 10110.
