We look at the division of 12644753 by 447 
Our goal is to divide 12644753 by 447.

Advancing to step 1:
The number 447 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 447

Advancing to step 2:
447 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 447

On to step 3:
When dividing 126 by 447, we get 0 with a remainder of 126.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 126 and we're left with 126.
Append the next digit (4) from the dividend to 126 and continue with: 1264 / 447

On to step 4:
447 goes into 1264 2 times with a remainder of 370.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 894 from 1264, we get 370.
Fetch the next digit (4) from the dividend, attach it to 370 and continue: 3704 / 447

Moving on to step 5:
When dividing 3704 by 447, we get 8 with a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 3576 from 3704, we get 128.
Append the next digit (7) from the dividend to 128 and continue with: 1287 / 447

Step 6:
When dividing 1287 by 447, we get 2 with a remainder of 393.
Write down 2 as next digit of the result. 
Result so far: 282.0
The remainder is 393 after subtracting 894 from 1287.
Take the next digit (5) from the dividend and append it to 393, then repeat: 3935 / 447

Going ahead to step 7:
447 goes into 3935 8 times with a remainder of 359.
The number 8 becomes the next digit in our result. 
Result so far: 2828.0
Subtracting 3576 from 3935 leaves us with 359.
Include the next digit (3) from the dividend after 359, then repeat: 3593 / 447

Going ahead to step 8:
3593 divided by 447 is 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 28288.0
Subtract 3576 from 3593 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 447 is 0 with a remainder of 170.
The next digit of our result is 0. 
Result so far: 28288.0
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
447 can be fit into 1700 3 times, resulting in a remainder of 359.
The number 3 becomes the next digit in our result. 
Result so far: 28288.03
Subtracting 1341 from 1700 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 11:
If we divide 3590 by 447, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 28288.038
Subtract 3576 from 3590 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
447 goes into 140 0 times with a remainder of 140.
The next digit of our result is 0. 
Result so far: 28288.038
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 13:
The number 447 fits into 1400 3 times, leaving a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 28288.03803
Deduct 1341 from 1400 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 14:
When dividing 590 by 447, we get 1 with a remainder of 143.
Use 1 as the next digit of our solution. 
Result so far: 28288.038031
The remainder is 143 after subtracting 447 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 15:
447 can be fit into 1430 3 times, resulting in a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 28288.0380313
If we take 1341 away from 1430, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 16:
447 goes into 890 1 times with a remainder of 443.
Put 1 as the next digit of the answer. 
Result so far: 28288.03803131
If we take 447 away from 890, we end up with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

The final result is 28288.03803131 with a remainder of 4.43e-07.
