We look at the division of 12530518 by 23 
Let's see how many times 23 fits into 12530518.

Advancing to step 1:
23 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 23

Step 2:
The number 23 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 23

Moving on to step 3:
If we divide 125 by 23, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 10 after subtracting 115 from 125.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 23

Step 4:
The number 23 fits into 103 4 times, leaving a remainder of 11.
The next digit of our result is 4. 
Result so far: 54.0
If we take 92 away from 103, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 23

Moving on to step 5:
110 divided by 23 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 544.0
Subtracting 92 from 110 leaves us with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 23

Step 6:
23 can be fit into 185 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 5448.0
Subtract 184 from 185 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 23

Advancing to step 7:
The number 23 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 54480.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 23

Advancing to step 8:
23 goes into 118 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 544805.0
Subtract 115 from 118 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
30 divided by 23 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 544805.1
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 544805.13
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
When dividing 10 by 23, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 544805.13
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
23 goes into 100 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 544805.1304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
23 goes into 80 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 544805.13043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
If we divide 110 by 23, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 544805.130434
Deduct 92 from 110 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 15:
23 can be fit into 180 7 times, resulting in a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 544805.1304347
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 16:
If we divide 190 by 23, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 544805.13043478
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 544805.13043478 and a remainder of 6e-09.
