To determine the number of variables present in the expression \(4x + 2y - 82b\), we first identify the variables in the expression.
The expression contains three variables: \(x\), \(y\), and \(b\).
When dividing, if we do not have any specific divisor provided, the variables in the quotient will still be present based on the original expression. Therefore, when dividing the expression \(4x + 2y - 82b\), the resulting quotient will include all three variables unless a specific variable is eliminated or the expression is simplified under certain conditions.
Therefore, the final answer would be that there are 3 variables present in the quotient.
