The number given to be divided, is called the dividend. The number of times the divisor is contained in the dividend is called the quotient. The remainder, if there be any, will be less than the divisor. PROOF. Multiply the quotient by the divisor; to the product add the remainder, and the sum will be equal to the dividend, if the work be right. EXAMPLES 3)2768954584 Rem.

Multiply the first divisor by the last remainder, and to the product add the first remainder, which will give the true one. EXAMPLES.
