Do the quotients always have the same number of digits when diving 3digit numbers by 1 digit numbers

No.

example: 123 : 3 = 41 (2 digits)

425 : 5 = 85 (2 digits)

but, if 428 : 2 = 214, which gives us 3 digits but not 2

∴, the quotient doesn't always have the no. of digits when we divide 3 digit no. s by 1 digit no. s.
