To solve the arithmetic expression:

27289347474747484920102 - 2828393930339392939393929

we can subtract each digit column by column, similar to how we would subtract numbers on paper. Starting from the rightmost column, subtract each digit:

      2  7  2  8  9  3  4  7  4  7  4  7  4  7  4  8  4  9  2  0  1  0  2
   -  2  8  2  8  3  9  3  9  3  9  3  9  3  9  2  9  3  9  3  9  3  9  2  9

Starting from the rightmost column, we subtract 2 from 9, which gives us 7. We write down 7 below. Moving to the next column, we subtract 9 from 9, which results in 0. We write down 0 below. Continuing this process column by column, we get:

      2  7  2  8  9  3  4  7  4  7  4  7  4  7  4  8  4  9  2  0  1  0  2
   -  2  8  2  8  3  9  3  9  3  9  3  9  3  9  2  9  3  9  3  9  3  9  2  9

             4  5  9  9  6  5  0
