We look at the division of 128564 by 12 
We want to divide 128564 by 12.

Let's proceed to step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 12

Let's proceed to step 2:
When dividing 12 by 12, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 12 from 12 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 12

Going ahead to step 3:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 12

On to step 4:
12 goes into 85 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
The remainder is 1 after subtracting 84 from 85.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 12

Let's proceed to step 5:
When dividing 16 by 12, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1071.0
If we subtract 12 from 16, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 12

Moving on to step 6:
If we divide 44 by 12, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 10713.0
Subtracting 36 from 44 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 10713.6
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 12 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 10713.66
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 10713.66 and a remainder of 0.008.
