"The Nine Chapters on the Mathematical Art" is an ancient Chinese mathematical text, which records: "If it can be halved, then halve it; if not, juxtapose the numerator and denominator, subtract the lesser from the greater, continue to subtract in turn, seeking their equality. Use the equal number to reduce them." This passage describes an important method for finding the greatest common divisor of two numbers, known as the "method of successive subtraction." When student Ai Xue was using the "method of successive subtraction" to find the greatest common divisor of 588 and 315, the second step of the calculation process was accidentally damaged, making the process incomplete, "(588,315)→(⋅,315)→(273,42)→…" The damaged part of Ai Xue's calculation process should be filled with ______.
