We look at the division of 458300 by 23 
We want to divide 458300 by 23.

Step 1:
If we divide 4 by 23, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 23

Moving on to step 2:
When dividing 45 by 23, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 23 from 45 to get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 23

On to step 3:
228 divided by 23 is 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 207 from 228 and we're left with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 23

Step 4:
23 goes into 213 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 199.0
If we take 207 away from 213, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 23

Moving on to step 5:
If we divide 60 by 23, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1992.0
If we subtract 46 from 60, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 23

Advancing to step 6:
If we divide 140 by 23, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 19926.0
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 23, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19926.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 23, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 19926.08
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 23 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 19926.086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
When dividing 220 by 23, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 19926.0869
If we take 207 away from 220, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 19926.08695
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
150 divided by 23 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 19926.086956
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
120 divided by 23 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 19926.0869565
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 19926.08695652
Subtracting 46 from 50 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 19926.08695652 with a remainder of 4e-09.
