We look at the division of 443431 by 12 
Our goal is to divide 443431 by 12.

Let's proceed to step 1:
12 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 12

Advancing to step 2:
44 divided by 12 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 36 from 44 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 12

Let's proceed to step 3:
If we divide 83 by 12, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 11 after subtracting 72 from 83.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 12

Step 4:
The number 12 fits into 114 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 369.0
Deduct 108 from 114 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 12

Going ahead to step 5:
12 can be fit into 63 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 3695.0
Subtracting 60 from 63 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 12

Step 6:
31 divided by 12 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 36952.0
Deduct 24 from 31 and we're left 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.

Going ahead to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 36952.5
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
12 goes into 100 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 36952.58
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.

On to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 36952.583
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.

Advancing to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 36952.5833
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.

The final result is 36952.5833 with a remainder of 4e-05.
