Let's divide 20665352 by 864
We want to figure out the number of times 20665352 can be divided by 864.

Advancing to step 1:
864 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 864

Let's proceed to step 2:
864 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 864

Let's proceed to step 3:
The number 864 fits into 206 0 times, leaving a remainder of 206.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 206, we end up with 206.
Bring next digit (6) of the dividend behind the 206 and repeat the process: 2066 / 864

On to step 4:
864 goes into 2066 2 times with a remainder of 338.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1728 away from 2066, we end up with 338.
Fetch the next digit (5) from the dividend, attach it to 338 and continue: 3385 / 864

Step 5:
864 can be fit into 3385 3 times, resulting in a remainder of 793.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 793 after subtracting 2592 from 3385.
Bring next digit (3) of the dividend behind the 793 and repeat the process: 7933 / 864

Moving on to step 6:
If we divide 7933 by 864, we get 9 and a remainder of 157.
Use 9 as the next digit of our solution. 
Result so far: 239.0
If we subtract 7776 from 7933, we get 157.
Grab the next digit (5) from the dividend, add it to 157, then carry on: 1575 / 864

Going ahead to step 7:
The number 864 fits into 1575 1 times, leaving a remainder of 711.
Put 1 as the next digit of the answer. 
Result so far: 2391.0
Deduct 864 from 1575 and we're left with 711.
Fetch the next digit (2) from the dividend, attach it to 711 and continue: 7112 / 864

Step 8:
864 can be fit into 7112 8 times, resulting in a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 23918.0
Deduct 6912 from 7112 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 9:
2000 divided by 864 is 2 with a remainder of 272.
The next digit of our result is 2. 
Result so far: 23918.2
If we subtract 1728 from 2000, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 10:
864 goes into 2720 3 times with a remainder of 128.
Write down 3 as next digit of the result. 
Result so far: 23918.23
The remainder is 128 after subtracting 2592 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 11:
1280 divided by 864 is 1 with a remainder of 416.
The number 1 becomes the next digit in our result. 
Result so far: 23918.231
If we take 864 away from 1280, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 12:
4160 divided by 864 is 4 with a remainder of 704.
Write down 4 as next digit of the result. 
Result so far: 23918.2314
Subtract 3456 from 4160 to get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Step 13:
7040 divided by 864 is 8 with a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 23918.23148
Subtracting 6912 from 7040 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 14:
1280 divided by 864 is 1 with a remainder of 416.
Use 1 as the next digit of our solution. 
Result so far: 23918.231481
Subtract 864 from 1280 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 15:
When dividing 4160 by 864, we get 4 with a remainder of 704.
Put 4 as the next digit of the answer. 
Result so far: 23918.2314814
Deduct 3456 from 4160 and we're left with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

On to step 16:
7040 divided by 864 is 8 with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 23918.23148148
If we take 6912 away from 7040, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 23918.23148148 with a remainder of 1.28e-07.
