(a)
473270 = 400000 + _____ + 200 + 70
473270 = 400000 + _____ + 270
473270 - 400000 - 270 = 73000
(b)
523834 = _____ + 20000 + 3000 + 800 + 30 + 4

523834 - 23834 = 500000
(c)
262431 = 200000 + 60000 + _____ + 400 + 30 + 1
262431 = 260000 + _____ + 431
262431 - 260000 - 431 = 2000
(d)
856876 = 800000 + 50000 + 6000 + _____ + 70 + 6
856876 = 856000 + _____ + 76
856876 - 856000 - 76 = 800
