We look at the division of 3189 by 12 
Our goal is to divide 3189 by 12.

Step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 12

Step 2:
The number 12 fits into 31 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 7 after subtracting 24 from 31.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 12

Let's proceed to step 3:
12 goes into 78 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 72 from 78, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

Advancing to step 4:
The number 12 fits into 69 5 times, leaving a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 265.0
If we subtract 60 from 69, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 5:
90 divided by 12 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 265.7
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 265.75
Deduct 60 from 60 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
12 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 265.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 265.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 265.75, and the remainder is 0.0.
