16505589 ÷ 868 
We want to figure out the number of times 16505589 can be divided by 868.

Let's proceed to step 1:
If we divide 1 by 868, we get 0 and 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.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 868

Going ahead to step 2:
The number 868 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 868

Step 3:
If we divide 165 by 868, we get 0 and a remainder of 165.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 165, we get 165.
Fetch the next digit (0) from the dividend, attach it to 165 and continue: 1650 / 868

Step 4:
868 can be fit into 1650 1 times, resulting in a remainder of 782.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 868 from 1650, we get 782.
Append the next digit (5) from the dividend to 782 and continue with: 7825 / 868

On to step 5:
7825 divided by 868 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 7812 from 7825, we get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 868

Going ahead to step 6:
868 can be fit into 135 0 times, resulting in a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 190.0
The remainder is 135 after subtracting 0 from 135.
Append the next digit (8) from the dividend to 135 and continue with: 1358 / 868

Let's proceed to step 7:
1358 divided by 868 is 1 with a remainder of 490.
Put 1 as the next digit of the answer. 
Result so far: 1901.0
If we take 868 away from 1358, we end up with 490.
Take the next digit (9) from the dividend and append it to 490, then repeat: 4909 / 868

Going ahead to step 8:
4909 divided by 868 is 5 with a remainder of 569.
The number 5 becomes the next digit in our result. 
Result so far: 19015.0
If we take 4340 away from 4909, we end up with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Let's proceed to step 9:
When dividing 5690 by 868, we get 6 with a remainder of 482.
The number 6 becomes the next digit in our result. 
Result so far: 19015.6
Deduct 5208 from 5690 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Step 10:
The number 868 fits into 4820 5 times, leaving a remainder of 480.
Use 5 as the next digit of our solution. 
Result so far: 19015.65
The remainder is 480 after subtracting 4340 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 11:
The number 868 fits into 4800 5 times, leaving a remainder of 460.
The number 5 becomes the next digit in our result. 
Result so far: 19015.655
If we take 4340 away from 4800, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

After the division, we end up with 19015.655 and a remainder of 0.046.
