We divide 19905124 by 864
Our goal is to divide 19905124 by 864.

Let's proceed to step 1:
1 divided by 864 is 0 with 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.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 864

Let's proceed to step 2:
864 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 864

Step 3:
864 goes into 199 0 times with a remainder of 199.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 199 after subtracting 0 from 199.
Grab the next digit (0) from the dividend, add it to 199, then carry on: 1990 / 864

On to step 4:
864 can be fit into 1990 2 times, resulting in a remainder of 262.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1728 from 1990, we get 262.
Include the next digit (5) from the dividend after 262, then repeat: 2625 / 864

Going ahead to step 5:
2625 divided by 864 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 2592 from 2625 leaves us with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 864

Let's proceed to step 6:
The number 864 fits into 331 0 times, leaving a remainder of 331.
Use 0 as the next digit of our solution. 
Result so far: 230.0
The remainder is 331 after subtracting 0 from 331.
Include the next digit (2) from the dividend after 331, then repeat: 3312 / 864

Let's proceed to step 7:
864 goes into 3312 3 times with a remainder of 720.
The number 3 becomes the next digit in our result. 
Result so far: 2303.0
Deduct 2592 from 3312 and we're left with 720.
Take the next digit (4) from the dividend and append it to 720, then repeat: 7204 / 864

Step 8:
If we divide 7204 by 864, we get 8 and a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 23038.0
The remainder is 292 after subtracting 6912 from 7204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 9:
If we divide 2920 by 864, we get 3 and a remainder of 328.
Write down 3 as next digit of the result. 
Result so far: 23038.3
If we subtract 2592 from 2920, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 10:
864 can be fit into 3280 3 times, resulting in a remainder of 688.
Record the quotient 3 as the next digit in the result. 
Result so far: 23038.33
Subtract 2592 from 3280 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

After the division, we end up with 23038.33 and a remainder of 0.688.
