Answer:

Step-by-step explanation:
Given

Required
Determine the remainder
Write down the first digit i.e. 1. So, we have:

--------------------------------

Multiply that 1 by the divisor (1) i.e. 
Write down the result under the next digit i.e. (under 2)


--------------------------------

Sum 2 and 1 i.e 


--------------------------------
Multiply that 3 by the divisor (1) i.e. 
Write down the result under the next digit i.e. (under -3)


--------------------------------
Sum -3 and 3 i.e 


--------------------------------

Multiply that 0 by the divisor (1) i.e. 
Write down the result under the next digit i.e. (under 3)


--------------------------------

Sum 3 and 0 i.e 
Since there is no other computation to do, the result of the last sum is the remainder.
So:

5+10=15
or 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1
Your answer should be -8y + 6.6z + 10
−15.82x + 20.042
