15440975 ÷ 647 
We're looking to find how many times 647 goes into 15440975.

Going ahead to step 1:
The number 647 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 647

Moving on to step 2:
When dividing 15 by 647, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 647

Going ahead to step 3:
If we divide 154 by 647, we get 0 and a remainder of 154.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 154 to get 154.
Take the next digit (4) from the dividend and append it to 154, then repeat: 1544 / 647

Step 4:
647 goes into 1544 2 times with a remainder of 250.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 250 after subtracting 1294 from 1544.
Include the next digit (0) from the dividend after 250, then repeat: 2500 / 647

Let's proceed to step 5:
If we divide 2500 by 647, we get 3 and a remainder of 559.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 1941 from 2500 leaves us with 559.
Fetch the next digit (9) from the dividend, attach it to 559 and continue: 5599 / 647

Going ahead to step 6:
5599 divided by 647 is 8 with a remainder of 423.
The next digit of our result is 8. 
Result so far: 238.0
If we subtract 5176 from 5599, we get 423.
Grab the next digit (7) from the dividend, add it to 423, then carry on: 4237 / 647

Going ahead to step 7:
647 can be fit into 4237 6 times, resulting in a remainder of 355.
The next digit of our result is 6. 
Result so far: 2386.0
If we take 3882 away from 4237, we end up with 355.
Take the next digit (5) from the dividend and append it to 355, then repeat: 3555 / 647

Going ahead to step 8:
647 goes into 3555 5 times with a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 23865.0
If we take 3235 away from 3555, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 9:
647 goes into 3200 4 times with a remainder of 612.
The next digit of our result is 4. 
Result so far: 23865.4
Deduct 2588 from 3200 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 10:
647 goes into 6120 9 times with a remainder of 297.
Record the quotient 9 as the next digit in the result. 
Result so far: 23865.49
Subtracting 5823 from 6120 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 11:
2970 divided by 647 is 4 with a remainder of 382.
The next digit of our result is 4. 
Result so far: 23865.494
Deduct 2588 from 2970 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 12:
The number 647 fits into 3820 5 times, leaving a remainder of 585.
Write down 5 as next digit of the result. 
Result so far: 23865.4945
Deduct 3235 from 3820 and we're left with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Going ahead to step 13:
647 goes into 5850 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 23865.49459
If we subtract 5823 from 5850, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
270 divided by 647 is 0 with a remainder of 270.
The next digit of our result is 0. 
Result so far: 23865.49459
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 15:
When dividing 2700 by 647, we get 4 with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 23865.4945904
Deduct 2588 from 2700 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 16:
The number 647 fits into 1120 1 times, leaving a remainder of 473.
The number 1 becomes the next digit in our result. 
Result so far: 23865.49459041
If we take 647 away from 1120, we end up with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

The quotient of the division is 23865.49459041, and the remainder is 4.73e-07.
