If a number is divided by 19, the quotient is twice the remainder, and the number is several times the remainder How is it calculated?

If a number is divided by 19, the quotient is twice the remainder, and the number is several times the remainder How is it calculated?

Let this number be a and the remainder be B
a/19=2b.b
a=38b+b
a=39b
A: that's 39 times the remainder

If a three digit number less than 500 is divided by 86, the quotient and the remainder are the same. What is the maximum number of the three digits

Let the quotient be x, the quotient and the remainder are the same, so the remainder is also X
Divisor = divisor × quotient + remainder
86x+x
