We look at the division of 12495101 by 817 
Our goal is to divide 12495101 by 817.

Moving on to step 1:
817 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 817

On to step 2:
817 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 817

Step 3:
817 can be fit into 124 0 times, resulting in a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 124 after subtracting 0 from 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 817

Let's proceed to step 4:
817 goes into 1249 1 times with a remainder of 432.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 817 from 1249 to get 432.
Fetch the next digit (5) from the dividend, attach it to 432 and continue: 4325 / 817

Step 5:
When dividing 4325 by 817, we get 5 with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 4085 from 4325, we get 240.
Grab the next digit (1) from the dividend, add it to 240, then carry on: 2401 / 817

Moving on to step 6:
817 can be fit into 2401 2 times, resulting in a remainder of 767.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we subtract 1634 from 2401, we get 767.
Bring next digit (0) of the dividend behind the 767 and repeat the process: 7670 / 817

Moving on to step 7:
817 can be fit into 7670 9 times, resulting in a remainder of 317.
Record the quotient 9 as the next digit in the result. 
Result so far: 1529.0
Subtracting 7353 from 7670 leaves us with 317.
Fetch the next digit (1) from the dividend, attach it to 317 and continue: 3171 / 817

On to step 8:
3171 divided by 817 is 3 with a remainder of 720.
Write down 3 as next digit of the result. 
Result so far: 15293.0
If we subtract 2451 from 3171, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 9:
817 goes into 7200 8 times with a remainder of 664.
Write down 8 as next digit of the result. 
Result so far: 15293.8
If we subtract 6536 from 7200, we get 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 10:
817 can be fit into 6640 8 times, resulting in a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 15293.88
Subtract 6536 from 6640 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 15293.88 with a remaining 0.104.
