We're dividing 128947 by 12 
Let's see how many times 12 fits into 128947.

Going ahead to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 12

Let's proceed to step 2:
The number 12 fits into 12 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 12 from 12, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 12

Step 3:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 8, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 12

Moving on to step 4:
When dividing 89 by 12, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 107.0
Deduct 84 from 89 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 12

Going ahead to step 5:
12 can be fit into 54 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1074.0
If we subtract 48 from 54, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 12

Going ahead to step 6:
The number 12 fits into 67 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 10745.0
If we take 60 away from 67, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 12, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10745.5
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 10745.58
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 10745.583
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
12 goes into 40 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 10745.5833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 10745.5833 with a remaining 4e-05.
