(a)
240214 = 200000 + _____ + 200 + 14
240214 = 200000 + _____ + 214
240214 - 200000 - 214 = 40000
(b)
556157 = _____ + 50000 + 6000 + 100 + 50 + 7

556157 - 56157 = 500000
(c)
313398 = 300000 + 10000 + _____ + 300 + 90 + 8
313398 = 310000 + _____ + 398
313398 - 310000 - 398 = 3000
(d)
862638 = 800000 + 60000 + 2000 + _____ + 30 + 8
862638 = 862000 + _____ + 38
862638 - 862000 - 38 = 600
