Can anyone me with this division and remainder problem?

[Victoriacv]

Is there any chance someone can help me solve this? Music teacher with absolutely no idea how to solve this. Thanl you so much.

? w!81 = 26r3 (the goal is to find the first number, and explain how you figured it out)

Can you explain the notation? It is not standard mathematical notation.

Perhaps @Victoriacv meant to type: w divided by 81 equals 26 remainder 3. If that is the case, then you can rewrite as (w / 81) = 26 + (3/81), then multiply both sides by 81 and get the value of w.
