We divide 661718 by 23
We want to figure out the number of times 661718 can be divided by 23.

Moving on to step 1:
The number 23 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 23

Going ahead to step 2:
23 goes into 66 2 times with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 46 away from 66, we end up with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 23

On to step 3:
201 divided by 23 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 184 away from 201, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 23

On to step 4:
23 can be fit into 177 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 287.0
Subtract 161 from 177 to get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 23

Let's proceed to step 5:
The number 23 fits into 161 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 2877.0
If we take 161 away from 161, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 23

Moving on to step 6:
The number 23 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 28770.0
The remainder is 8 after subtracting 0 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
When dividing 80 by 23, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 28770.3
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
23 goes into 110 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 28770.34
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
When dividing 180 by 23, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 28770.347
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 28770.3478
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.

Moving on to step 11:
If we divide 60 by 23, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 28770.34782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 28770.347826
If we subtract 138 from 140, we 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 13:
23 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 28770.347826
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 14:
200 divided by 23 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 28770.34782608
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 28770.34782608 with a remainder of 1.6e-08.
