13172819 ÷ 975 
We want to divide 13172819 by 975.

Moving on to step 1:
When dividing 1 by 975, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 975

Step 2:
975 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 975

Advancing to step 3:
975 can be fit into 131 0 times, resulting in a remainder of 131.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 131 and we're left with 131.
Append the next digit (7) from the dividend to 131 and continue with: 1317 / 975

Going ahead to step 4:
975 goes into 1317 1 times with a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 975 away from 1317, we end up with 342.
Fetch the next digit (2) from the dividend, attach it to 342 and continue: 3422 / 975

Moving on to step 5:
3422 divided by 975 is 3 with a remainder of 497.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 2925 away from 3422, we end up with 497.
Take the next digit (8) from the dividend and append it to 497, then repeat: 4978 / 975

Moving on to step 6:
975 goes into 4978 5 times with a remainder of 103.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Subtracting 4875 from 4978 leaves us with 103.
Grab the next digit (1) from the dividend, add it to 103, then carry on: 1031 / 975

On to step 7:
The number 975 fits into 1031 1 times, leaving a remainder of 56.
The next digit of our result is 1. 
Result so far: 1351.0
Subtracting 975 from 1031 leaves us with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 975

Going ahead to step 8:
975 can be fit into 569 0 times, resulting in a remainder of 569.
Use 0 as the next digit of our solution. 
Result so far: 13510.0
If we subtract 0 from 569, we get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

On to step 9:
If we divide 5690 by 975, we get 5 and a remainder of 815.
Put 5 as the next digit of the answer. 
Result so far: 13510.5
Subtract 4875 from 5690 to get 815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8150, and continue the process.

Step 10:
When dividing 8150 by 975, we get 8 with a remainder of 350.
Put 8 as the next digit of the answer. 
Result so far: 13510.58
If we take 7800 away from 8150, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 11:
When dividing 3500 by 975, we get 3 with a remainder of 575.
The next digit of our result is 3. 
Result so far: 13510.583
The remainder is 575 after subtracting 2925 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Step 12:
975 goes into 5750 5 times with a remainder of 875.
The next digit of our result is 5. 
Result so far: 13510.5835
If we subtract 4875 from 5750, we get 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Advancing to step 13:
8750 divided by 975 is 8 with a remainder of 950.
Record the quotient 8 as the next digit in the result. 
Result so far: 13510.58358
If we subtract 7800 from 8750, we get 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Let's proceed to step 14:
975 can be fit into 9500 9 times, resulting in a remainder of 725.
The number 9 becomes the next digit in our result. 
Result so far: 13510.583589
Subtract 8775 from 9500 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Let's proceed to step 15:
When dividing 7250 by 975, we get 7 with a remainder of 425.
The next digit of our result is 7. 
Result so far: 13510.5835897
The remainder is 425 after subtracting 6825 from 7250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 16:
When dividing 4250 by 975, we get 4 with a remainder of 350.
Put 4 as the next digit of the answer. 
Result so far: 13510.58358974
Subtracting 3900 from 4250 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 13510.58358974, with a leftover of 3.5e-07.
