458608 ÷ 23 
Let's see how many times 23 fits into 458608.

Moving on to step 1:
4 divided by 23 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 23

Advancing to step 2:
If we divide 45 by 23, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 23 from 45 leaves us with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 23

Step 3:
23 can be fit into 228 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 207 from 228 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 23

On to step 4:
The number 23 fits into 216 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 199.0
Subtract 207 from 216 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 23

Step 5:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 1993.0
If we subtract 69 from 90, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 23

Advancing to step 6:
23 can be fit into 218 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 19939.0
Deduct 207 from 218 and we're left 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.

Moving on to step 7:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 19939.4
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.

Step 8:
23 goes into 180 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 19939.47
Subtracting 161 from 180 leaves us 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.

Advancing to step 9:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 19939.478
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.

Let's proceed to step 10:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 19939.4782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
When dividing 140 by 23, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 19939.47826
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.

Step 12:
If we divide 20 by 23, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19939.47826
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 13:
23 goes into 200 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 19939.4782608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
If we divide 160 by 23, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 19939.47826086
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.

The final outcome is 19939.47826086, with a leftover of 2.2e-08.
