We're dividing 17039809 by 488 
We want to figure out the number of times 17039809 can be divided by 488.

Going ahead to step 1:
1 divided by 488 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 488

Let's proceed to step 2:
If we divide 17 by 488, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 488

On to step 3:
If we divide 170 by 488, we get 0 and a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 170 after subtracting 0 from 170.
Grab the next digit (3) from the dividend, add it to 170, then carry on: 1703 / 488

Going ahead to step 4:
488 goes into 1703 3 times with a remainder of 239.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1464 from 1703, we get 239.
Bring next digit (9) of the dividend behind the 239 and repeat the process: 2399 / 488

Advancing to step 5:
2399 divided by 488 is 4 with a remainder of 447.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 1952 from 2399 and we're left with 447.
Include the next digit (8) from the dividend after 447, then repeat: 4478 / 488

Step 6:
488 goes into 4478 9 times with a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 349.0
Deduct 4392 from 4478 and we're left with 86.
Take the next digit (0) from the dividend and append it to 86, then repeat: 860 / 488

Step 7:
The number 488 fits into 860 1 times, leaving a remainder of 372.
The number 1 becomes the next digit in our result. 
Result so far: 3491.0
If we take 488 away from 860, we end up with 372.
Include the next digit (9) from the dividend after 372, then repeat: 3729 / 488

Advancing to step 8:
3729 divided by 488 is 7 with a remainder of 313.
Use 7 as the next digit of our solution. 
Result so far: 34917.0
The remainder is 313 after subtracting 3416 from 3729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 9:
3130 divided by 488 is 6 with a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 34917.6
If we subtract 2928 from 3130, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
488 can be fit into 2020 4 times, resulting in a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 34917.64
Deduct 1952 from 2020 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
When dividing 680 by 488, we get 1 with a remainder of 192.
The number 1 becomes the next digit in our result. 
Result so far: 34917.641
The remainder is 192 after subtracting 488 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
If we divide 1920 by 488, we get 3 and a remainder of 456.
Use 3 as the next digit of our solution. 
Result so far: 34917.6413
Subtracting 1464 from 1920 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 13:
When dividing 4560 by 488, we get 9 with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 34917.64139
The remainder is 168 after subtracting 4392 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 14:
488 goes into 1680 3 times with a remainder of 216.
Record the quotient 3 as the next digit in the result. 
Result so far: 34917.641393
Subtract 1464 from 1680 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 15:
When dividing 2160 by 488, we get 4 with a remainder of 208.
The next digit of our result is 4. 
Result so far: 34917.6413934
If we take 1952 away from 2160, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 16:
2080 divided by 488 is 4 with a remainder of 128.
The next digit of our result is 4. 
Result so far: 34917.64139344
The remainder is 128 after subtracting 1952 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 34917.64139344 and a remainder of 1.28e-07.
