Let's divide 10172902 by 868
Our goal is to divide 10172902 by 868.

Advancing to step 1:
1 divided by 868 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 868

Let's proceed to step 2:
If we divide 10 by 868, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 868

Step 3:
If we divide 101 by 868, we get 0 and a remainder of 101.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 101 after subtracting 0 from 101.
Grab the next digit (7) from the dividend, add it to 101, then carry on: 1017 / 868

Advancing to step 4:
The number 868 fits into 1017 1 times, leaving a remainder of 149.
The next digit of our result is 1. 
Result so far: 1.0
If we take 868 away from 1017, we end up with 149.
Fetch the next digit (2) from the dividend, attach it to 149 and continue: 1492 / 868

Going ahead to step 5:
The number 868 fits into 1492 1 times, leaving a remainder of 624.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 868 from 1492, we get 624.
Append the next digit (9) from the dividend to 624 and continue with: 6249 / 868

Moving on to step 6:
When dividing 6249 by 868, we get 7 with a remainder of 173.
The next digit of our result is 7. 
Result so far: 117.0
Deduct 6076 from 6249 and we're left with 173.
Fetch the next digit (0) from the dividend, attach it to 173 and continue: 1730 / 868

Step 7:
When dividing 1730 by 868, we get 1 with a remainder of 862.
The number 1 becomes the next digit in our result. 
Result so far: 1171.0
The remainder is 862 after subtracting 868 from 1730.
Include the next digit (2) from the dividend after 862, then repeat: 8622 / 868

Advancing to step 8:
8622 divided by 868 is 9 with a remainder of 810.
Use 9 as the next digit of our solution. 
Result so far: 11719.0
Deduct 7812 from 8622 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Let's proceed to step 9:
When dividing 8100 by 868, we get 9 with a remainder of 288.
Use 9 as the next digit of our solution. 
Result so far: 11719.9
If we take 7812 away from 8100, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 10:
2880 divided by 868 is 3 with a remainder of 276.
Record the quotient 3 as the next digit in the result. 
Result so far: 11719.93
The remainder is 276 after subtracting 2604 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
When dividing 2760 by 868, we get 3 with a remainder of 156.
The number 3 becomes the next digit in our result. 
Result so far: 11719.933
The remainder is 156 after subtracting 2604 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Our division results in 11719.933 with a remaining 0.0156.
