17665549 ÷ 649 
We want to figure out the number of times 17665549 can be divided by 649.

Step 1:
When dividing 1 by 649, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 649

Advancing to step 2:
When dividing 17 by 649, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 649

Moving on to step 3:
649 goes into 176 0 times with a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 176, we get 176.
Append the next digit (6) from the dividend to 176 and continue with: 1766 / 649

Let's proceed to step 4:
When dividing 1766 by 649, we get 2 with a remainder of 468.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1298 from 1766 and we're left with 468.
Append the next digit (5) from the dividend to 468 and continue with: 4685 / 649

Let's proceed to step 5:
When dividing 4685 by 649, we get 7 with a remainder of 142.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 4543 from 4685 to get 142.
Grab the next digit (5) from the dividend, add it to 142, then carry on: 1425 / 649

Let's proceed to step 6:
The number 649 fits into 1425 2 times, leaving a remainder of 127.
Record the quotient 2 as the next digit in the result. 
Result so far: 272.0
Subtract 1298 from 1425 to get 127.
Grab the next digit (4) from the dividend, add it to 127, then carry on: 1274 / 649

On to step 7:
The number 649 fits into 1274 1 times, leaving a remainder of 625.
Write down 1 as next digit of the result. 
Result so far: 2721.0
If we subtract 649 from 1274, we get 625.
Include the next digit (9) from the dividend after 625, then repeat: 6259 / 649

On to step 8:
649 can be fit into 6259 9 times, resulting in a remainder of 418.
Write down 9 as next digit of the result. 
Result so far: 27219.0
Subtract 5841 from 6259 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 9:
The number 649 fits into 4180 6 times, leaving a remainder of 286.
Use 6 as the next digit of our solution. 
Result so far: 27219.6
Deduct 3894 from 4180 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
649 can be fit into 2860 4 times, resulting in a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 27219.64
Subtract 2596 from 2860 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 11:
If we divide 2640 by 649, we get 4 and a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 27219.644
If we subtract 2596 from 2640, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 27219.644 with a remaining 0.0044.
