459864 divided by 23 
We want to figure out the number of times 459864 can be divided by 23.

On to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 23

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
If we subtract 23 from 45, we get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 23

On to step 3:
The number 23 fits into 229 9 times, leaving a remainder of 22.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 22 after subtracting 207 from 229.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 23

Advancing to step 4:
If we divide 228 by 23, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 199.0
The remainder is 21 after subtracting 207 from 228.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 23

On to step 5:
23 can be fit into 216 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 1999.0
The remainder is 9 after subtracting 207 from 216.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 23

Moving on to step 6:
When dividing 94 by 23, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 19994.0
Subtract 92 from 94 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 23, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19994.0
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.

Going ahead to step 8:
23 goes into 200 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 19994.08
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.

Advancing to step 9:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 19994.086
Deduct 138 from 160 and we're left with 22.
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:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 19994.0869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
If we divide 130 by 23, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 19994.08695
If we take 115 away from 130, we end up 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.

On to step 12:
23 can be fit into 150 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 19994.086956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 19994.0869565
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
50 divided by 23 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 19994.08695652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 19994.08695652 and a remainder of 4e-09.
