We're dividing 20623456 by 862 
Let's see how many times 862 fits into 20623456.

Step 1:
2 divided by 862 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 862

Advancing to step 2:
862 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 862

Advancing to step 3:
206 divided by 862 is 0 with a remainder of 206.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 206 leaves us with 206.
Append the next digit (2) from the dividend to 206 and continue with: 2062 / 862

Advancing to step 4:
If we divide 2062 by 862, we get 2 and a remainder of 338.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1724 from 2062 leaves us with 338.
Include the next digit (3) from the dividend after 338, then repeat: 3383 / 862

On to step 5:
862 goes into 3383 3 times with a remainder of 797.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 2586 from 3383 leaves us with 797.
Bring next digit (4) of the dividend behind the 797 and repeat the process: 7974 / 862

Moving on to step 6:
7974 divided by 862 is 9 with a remainder of 216.
Write down 9 as next digit of the result. 
Result so far: 239.0
If we subtract 7758 from 7974, we get 216.
Fetch the next digit (5) from the dividend, attach it to 216 and continue: 2165 / 862

Moving on to step 7:
If we divide 2165 by 862, we get 2 and a remainder of 441.
Write down 2 as next digit of the result. 
Result so far: 2392.0
Subtract 1724 from 2165 to get 441.
Include the next digit (6) from the dividend after 441, then repeat: 4416 / 862

Advancing to step 8:
If we divide 4416 by 862, we get 5 and a remainder of 106.
Record the quotient 5 as the next digit in the result. 
Result so far: 23925.0
If we take 4310 away from 4416, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 9:
If we divide 1060 by 862, we get 1 and a remainder of 198.
Write down 1 as next digit of the result. 
Result so far: 23925.1
Deduct 862 from 1060 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Let's proceed to step 10:
862 can be fit into 1980 2 times, resulting in a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 23925.12
Subtract 1724 from 1980 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 11:
When dividing 2560 by 862, we get 2 with a remainder of 836.
The number 2 becomes the next digit in our result. 
Result so far: 23925.122
If we take 1724 away from 2560, we end up with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

After the division, we end up with 23925.122 and a remainder of 0.0836.
