We look at the division of 12585641 by 868 
We're looking to find how many times 868 goes into 12585641.

On to step 1:
The number 868 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 868

Advancing to step 2:
If we divide 12 by 868, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 868

Let's proceed to step 3:
When dividing 125 by 868, we get 0 with a remainder of 125.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 125 leaves us with 125.
Fetch the next digit (8) from the dividend, attach it to 125 and continue: 1258 / 868

Going ahead to step 4:
If we divide 1258 by 868, we get 1 and a remainder of 390.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 868 from 1258 and we're left with 390.
Fetch the next digit (5) from the dividend, attach it to 390 and continue: 3905 / 868

Advancing to step 5:
868 can be fit into 3905 4 times, resulting in a remainder of 433.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 433 after subtracting 3472 from 3905.
Include the next digit (6) from the dividend after 433, then repeat: 4336 / 868

Going ahead to step 6:
868 can be fit into 4336 4 times, resulting in a remainder of 864.
Put 4 as the next digit of the answer. 
Result so far: 144.0
The remainder is 864 after subtracting 3472 from 4336.
Include the next digit (4) from the dividend after 864, then repeat: 8644 / 868

Moving on to step 7:
8644 divided by 868 is 9 with a remainder of 832.
Write down 9 as next digit of the result. 
Result so far: 1449.0
Subtract 7812 from 8644 to get 832.
Bring next digit (1) of the dividend behind the 832 and repeat the process: 8321 / 868

Moving on to step 8:
8321 divided by 868 is 9 with a remainder of 509.
Use 9 as the next digit of our solution. 
Result so far: 14499.0
The remainder is 509 after subtracting 7812 from 8321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Advancing to step 9:
The number 868 fits into 5090 5 times, leaving a remainder of 750.
Record the quotient 5 as the next digit in the result. 
Result so far: 14499.5
Subtract 4340 from 5090 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 10:
868 goes into 7500 8 times with a remainder of 556.
The number 8 becomes the next digit in our result. 
Result so far: 14499.58
Subtracting 6944 from 7500 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 11:
If we divide 5560 by 868, we get 6 and a remainder of 352.
Record the quotient 6 as the next digit in the result. 
Result so far: 14499.586
The remainder is 352 after subtracting 5208 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 12:
868 can be fit into 3520 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 14499.5864
Subtract 3472 from 3520 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
868 can be fit into 480 0 times, resulting in a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 14499.5864
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 14:
The number 868 fits into 4800 5 times, leaving a remainder of 460.
Put 5 as the next digit of the answer. 
Result so far: 14499.586405
The remainder is 460 after subtracting 4340 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 15:
4600 divided by 868 is 5 with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 14499.5864055
If we take 4340 away from 4600, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 14499.5864055, with a leftover of 2.6e-06.
