664919 ÷ 23 
We're looking to find how many times 23 goes into 664919.

On to step 1:
23 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 23

Advancing to step 2:
66 divided by 23 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 46 away from 66, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 23

On to step 3:
The number 23 fits into 204 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 20 after subtracting 184 from 204.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 23

On to step 4:
209 divided by 23 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
The remainder is 2 after subtracting 207 from 209.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 23

Going ahead to step 5:
When dividing 21 by 23, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 2890.0
If we take 0 away from 21, we end up with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 23

Going ahead to step 6:
23 can be fit into 219 9 times, resulting in a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 28909.0
If we subtract 207 from 219, we 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.

Moving on to step 7:
120 divided by 23 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 28909.5
Deduct 115 from 120 and we're left 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.

On to step 8:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 28909.52
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.

Let's proceed to step 9:
If we divide 40 by 23, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 28909.521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
When dividing 170 by 23, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 28909.5217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
23 goes into 90 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 28909.52173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
If we divide 210 by 23, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 28909.521739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
30 divided by 23 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 28909.5217391
Subtracting 23 from 30 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 14:
23 goes into 70 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 28909.52173913
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.

The quotient of the division is 28909.52173913, and the remainder is 1e-09.
