We look at the division of 518450 by 23 
Let's see how many times 23 fits into 518450.

On to step 1:
23 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 23

On to step 2:
23 goes into 51 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 46 from 51 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 23

Advancing to step 3:
58 divided by 23 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 46 from 58 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 23

On to step 4:
124 divided by 23 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 225.0
If we take 115 away from 124, we end up with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 23

On to step 5:
When dividing 95 by 23, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 2254.0
Subtract 92 from 95 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 23

Step 6:
30 divided by 23 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 22541.0
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 22541.3
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 22541.3
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 23 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 22541.304
If we take 92 away from 100, we end up with 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 10:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 22541.3043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
110 divided by 23 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 22541.30434
If we take 92 away from 110, we end up 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.

On to step 12:
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: 22541.304347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 22541.3043478
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
The number 23 fits into 60 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 22541.30434782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 22541.30434782, with a leftover of 1.4e-08.
