Let's divide 664559 by 23
Our goal is to divide 664559 by 23.

Step 1:
23 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 23

On to step 2:
If we divide 66 by 23, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 46 from 66 and we're left with 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 23

Going ahead to step 3:
204 divided by 23 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 184 from 204 and we're left with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 23

On to step 4:
The number 23 fits into 205 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
Subtracting 184 from 205 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 23

Advancing to step 5:
The number 23 fits into 215 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 2889.0
If we subtract 207 from 215, we get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 23

Step 6:
23 goes into 89 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 28893.0
Subtract 69 from 89 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
When dividing 200 by 23, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 28893.8
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 8:
23 goes into 160 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 28893.86
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.

Let's proceed to step 9:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 28893.869
Deduct 207 from 220 and we're left 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.

Going ahead to step 10:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 28893.8695
If we subtract 115 from 130, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
23 goes into 150 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 28893.86956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
23 goes into 120 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 28893.869565
If we take 115 away from 120, we end up 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.

Advancing to step 13:
23 can be fit into 50 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 28893.8695652
Subtract 46 from 50 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 28893.86956521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 28893.86956521, with a leftover of 1.7e-08.
