Let's divide 20308392 by 864
Let's see how many times 864 fits into 20308392.

On to step 1:
864 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 864

Advancing to step 2:
If we divide 20 by 864, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 864

On to step 3:
If we divide 203 by 864, we get 0 and a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Fetch the next digit (0) from the dividend, attach it to 203 and continue: 2030 / 864

On to step 4:
864 can be fit into 2030 2 times, resulting in a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1728 from 2030 leaves us with 302.
Take the next digit (8) from the dividend and append it to 302, then repeat: 3028 / 864

Let's proceed to step 5:
3028 divided by 864 is 3 with a remainder of 436.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 2592 from 3028, we get 436.
Include the next digit (3) from the dividend after 436, then repeat: 4363 / 864

Going ahead to step 6:
864 can be fit into 4363 5 times, resulting in a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 235.0
Subtract 4320 from 4363 to get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 864

Let's proceed to step 7:
864 can be fit into 439 0 times, resulting in a remainder of 439.
Record the quotient 0 as the next digit in the result. 
Result so far: 2350.0
If we take 0 away from 439, we end up with 439.
Fetch the next digit (2) from the dividend, attach it to 439 and continue: 4392 / 864

Advancing to step 8:
If we divide 4392 by 864, we get 5 and a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 23505.0
Subtract 4320 from 4392 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
If we divide 720 by 864, we get 0 and a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 23505.0
Deduct 0 from 720 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 10:
The number 864 fits into 7200 8 times, leaving a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 23505.08
Deduct 6912 from 7200 and we're left 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 11:
When dividing 2880 by 864, we get 3 with a remainder of 288.
The next digit of our result is 3. 
Result so far: 23505.083
Deduct 2592 from 2880 and we're left 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 12:
864 goes into 2880 3 times with a remainder of 288.
Write down 3 as next digit of the result. 
Result so far: 23505.0833
Deduct 2592 from 2880 and we're left 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.

The quotient of the division is 23505.0833, and the remainder is 0.00288.
