It would leave a remainder of 1.
How do you divide Congruences?
The following theorem tells us when and with what can we divide a congruence. Essentially, it says that we can divide by a number that is relatively prime to the modulus. Theorem 3: ca ≡ cb ( mod m ) implies a ≡ b ( mod m ) if and only if (c, m) = 1.

What is mod math?
The modulo (or “modulus” or “mod”) is the remainder after dividing one number by another. Example: 100 mod 9 equals 1. Because 100/9 = 11 with a remainder of 1. Another example: 14 mod 12 equals 2. Because 14/12 = 1 with a remainder of 2.

How to calculate the modulo – an example
- Start by choosing the initial number (before performing the modulo operation).
- Choose the divisor.
- Divide one number by the other, rounding down: 250 / 24 = 10 .
- Multiply the divisor by the quotient.
- Subtract this number from your initial number (dividend).
