660910 divided by 23 
Let's see how many times 23 fits into 660910.

Let's proceed to step 1:
6 divided by 23 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 23

Advancing to step 2:
If we divide 66 by 23, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 46 from 66, we get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 23

Advancing to step 3:
23 can be fit into 200 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 16 after subtracting 184 from 200.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 23

Step 4:
The number 23 fits into 169 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 287.0
If we subtract 161 from 169, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 23

Advancing to step 5:
If we divide 81 by 23, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 2873.0
The remainder is 12 after subtracting 69 from 81.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 23

Going ahead to step 6:
23 can be fit into 120 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 28735.0
If we subtract 115 from 120, we 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 7:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 28735.2
If we subtract 46 from 50, we 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.

On to step 8:
23 goes into 40 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 28735.21
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.

Let's proceed to step 9:
When dividing 170 by 23, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 28735.217
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 10:
The number 23 fits into 90 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 28735.2173
Subtracting 69 from 90 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
23 can be fit into 210 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 28735.21739
Deduct 207 from 210 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 12:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 28735.217391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
23 can be fit into 70 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 28735.2173913
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.

On to step 14:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 28735.2173913
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 28735.2173913 and a remainder of 1e-08.
