20639023 ÷ 923 
Our goal is to divide 20639023 by 923.

Advancing to step 1:
2 divided by 923 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 923

Going ahead to step 2:
923 goes into 20 0 times with 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.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 923

Let's proceed to step 3:
923 can be fit into 206 0 times, resulting in a remainder of 206.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 206 leaves us with 206.
Bring next digit (3) of the dividend behind the 206 and repeat the process: 2063 / 923

Let's proceed to step 4:
If we divide 2063 by 923, we get 2 and a remainder of 217.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1846 from 2063, we get 217.
Fetch the next digit (9) from the dividend, attach it to 217 and continue: 2179 / 923

Moving on to step 5:
When dividing 2179 by 923, we get 2 with a remainder of 333.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1846 from 2179 to get 333.
Include the next digit (0) from the dividend after 333, then repeat: 3330 / 923

Moving on to step 6:
3330 divided by 923 is 3 with a remainder of 561.
Put 3 as the next digit of the answer. 
Result so far: 223.0
The remainder is 561 after subtracting 2769 from 3330.
Bring next digit (2) of the dividend behind the 561 and repeat the process: 5612 / 923

Let's proceed to step 7:
5612 divided by 923 is 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 2236.0
The remainder is 74 after subtracting 5538 from 5612.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 923

Step 8:
When dividing 743 by 923, we get 0 with a remainder of 743.
Put 0 as the next digit of the answer. 
Result so far: 22360.0
If we take 0 away from 743, we end up with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

On to step 9:
When dividing 7430 by 923, we get 8 with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 22360.8
The remainder is 46 after subtracting 7384 from 7430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
When dividing 460 by 923, we get 0 with a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 22360.8
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 11:
4600 divided by 923 is 4 with a remainder of 908.
Record the quotient 4 as the next digit in the result. 
Result so far: 22360.804
Subtract 3692 from 4600 to get 908.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9080, and continue the process.

On to step 12:
If we divide 9080 by 923, we get 9 and a remainder of 773.
Record the quotient 9 as the next digit in the result. 
Result so far: 22360.8049
Subtracting 8307 from 9080 leaves us with 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Step 13:
923 goes into 7730 8 times with a remainder of 346.
Write down 8 as next digit of the result. 
Result so far: 22360.80498
The remainder is 346 after subtracting 7384 from 7730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 14:
923 goes into 3460 3 times with a remainder of 691.
Use 3 as the next digit of our solution. 
Result so far: 22360.804983
Deduct 2769 from 3460 and we're left with 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

On to step 15:
923 can be fit into 6910 7 times, resulting in a remainder of 449.
The next digit of our result is 7. 
Result so far: 22360.8049837
Subtracting 6461 from 6910 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 16:
If we divide 4490 by 923, we get 4 and a remainder of 798.
The number 4 becomes the next digit in our result. 
Result so far: 22360.80498374
If we take 3692 away from 4490, we end up with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

In conclusion, the division gives 22360.80498374 with a balance of 7.98e-07.
