We look at the division of 15399756 by 447 
Our goal is to divide 15399756 by 447.

On to step 1:
1 divided by 447 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 447

Step 2:
447 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 447

On to step 3:
The number 447 fits into 153 0 times, leaving a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 153 to get 153.
Include the next digit (9) from the dividend after 153, then repeat: 1539 / 447

Advancing to step 4:
If we divide 1539 by 447, we get 3 and a remainder of 198.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1341 from 1539 and we're left with 198.
Bring next digit (9) of the dividend behind the 198 and repeat the process: 1989 / 447

Step 5:
447 goes into 1989 4 times with a remainder of 201.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 1788 from 1989, we get 201.
Append the next digit (7) from the dividend to 201 and continue with: 2017 / 447

Going ahead to step 6:
When dividing 2017 by 447, we get 4 with a remainder of 229.
Use 4 as the next digit of our solution. 
Result so far: 344.0
If we subtract 1788 from 2017, we get 229.
Grab the next digit (5) from the dividend, add it to 229, then carry on: 2295 / 447

Going ahead to step 7:
447 goes into 2295 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 3445.0
If we subtract 2235 from 2295, we get 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 447

Step 8:
The number 447 fits into 606 1 times, leaving a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 34451.0
Subtracting 447 from 606 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 9:
447 can be fit into 1590 3 times, resulting in a remainder of 249.
Write down 3 as next digit of the result. 
Result so far: 34451.3
Subtract 1341 from 1590 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 10:
2490 divided by 447 is 5 with a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 34451.35
If we take 2235 away from 2490, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 11:
447 can be fit into 2550 5 times, resulting in a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 34451.355
If we take 2235 away from 2550, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

In conclusion, the division gives 34451.355 with a balance of 0.0315.
