19516752 divided by 864 
We want to figure out the number of times 19516752 can be divided by 864.

On to step 1:
The number 864 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 864

Moving on to step 2:
If we divide 19 by 864, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 864

Moving on to step 3:
864 can be fit into 195 0 times, resulting in a remainder of 195.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 195 after subtracting 0 from 195.
Fetch the next digit (1) from the dividend, attach it to 195 and continue: 1951 / 864

Going ahead to step 4:
864 can be fit into 1951 2 times, resulting in a remainder of 223.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1728 from 1951, we get 223.
Fetch the next digit (6) from the dividend, attach it to 223 and continue: 2236 / 864

Moving on to step 5:
864 goes into 2236 2 times with a remainder of 508.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 1728 from 2236, we get 508.
Fetch the next digit (7) from the dividend, attach it to 508 and continue: 5087 / 864

Let's proceed to step 6:
The number 864 fits into 5087 5 times, leaving a remainder of 767.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
Subtract 4320 from 5087 to get 767.
Include the next digit (5) from the dividend after 767, then repeat: 7675 / 864

On to step 7:
If we divide 7675 by 864, we get 8 and a remainder of 763.
The next digit of our result is 8. 
Result so far: 2258.0
Subtracting 6912 from 7675 leaves us with 763.
Append the next digit (2) from the dividend to 763 and continue with: 7632 / 864

Step 8:
If we divide 7632 by 864, we get 8 and a remainder of 720.
Record the quotient 8 as the next digit in the result. 
Result so far: 22588.0
The remainder is 720 after subtracting 6912 from 7632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 9:
7200 divided by 864 is 8 with a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 22588.8
Subtracting 6912 from 7200 leaves us 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.

On to step 10:
If we divide 2880 by 864, we get 3 and a remainder of 288.
Use 3 as the next digit of our solution. 
Result so far: 22588.83
If we take 2592 away from 2880, 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.

Let's proceed to step 11:
864 goes into 2880 3 times with a remainder of 288.
The number 3 becomes the next digit in our result. 
Result so far: 22588.833
If we subtract 2592 from 2880, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 22588.833, with a leftover of 0.0288.
