The last six digits of the dividend are TB8475_11, which suggests that it is a product of 11 and some other number. When we divide the dividend by 11, we get a quotient of 10e2c39_1b4d_8ee3_b851_81d8b7 and a remainder of 3dd7f_11. The quotient can be written as 10e2c3...b7, where the ellipsis represents some digits that we do not know. To get the correct answer, we need to add a digit to the ellipsis such that the quotient is divisible by 11. This digit must be 1, because the sum of the odd-positioned digits (0+2+3+1+8+1 = 15) minus the sum of the even-positioned digits (9+4+5+8+1 = 27) is -12, which means that the difference between the two sums is a multiple of 11 (the digit in the units place does not affect this calculation). Therefore, the quotient is 10e2c3...b71, and the complete answer is 11ebb63d_1b4d_8ee4_b851_c77a28a63bf5_TB8475_11.
