67 is just 6. One way to do the division is to convert 50627 to decimal.
Another way is to divide progressively by 6, remembering that a "ten" in base 7 is 7.
So since 6 doesn't divide into 5 we take the first two digits and convert to decimal:
50=5×7+0=35. 35➗6=5 rem 5. The first digit of the quotient is 5.
Now multiply the remainder by 7: 7×5=35 and add on the next digit, which is 6: 35+6=41.
Divide 41 by 6 and we get 6 rem 5, so the next digit in the quotient is 6. So far we have 56 as the first two digits of the quotient.
Now multiply the remainder by 7: 7×5=35 and add on the last digit, which is 2: 35+2=37.
Divide 37 by 6 and we get 6 rem 1, so the last digit in the quotient is 6, making it 566 rem 1.
566 is also to base 7.
