Let's divide 657858 by 23
We want to divide 657858 by 23.

Going ahead to step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 23

On to step 2:
The number 23 fits into 65 2 times, leaving a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 46 from 65 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 23

On to step 3:
When dividing 197 by 23, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 13 after subtracting 184 from 197.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 23

Step 4:
23 can be fit into 138 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 286.0
If we subtract 138 from 138, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 23

Going ahead to step 5:
If we divide 5 by 23, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 2860.0
If we subtract 0 from 5, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 23

On to step 6:
If we divide 58 by 23, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 28602.0
Subtract 46 from 58 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.

Moving on to step 7:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 28602.5
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.

Advancing to step 8:
If we divide 50 by 23, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 28602.52
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.

Let's proceed to step 9:
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: 28602.521
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.

Step 10:
When dividing 170 by 23, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 28602.5217
Deduct 161 from 170 and we're left 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 can be fit into 90 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 28602.52173
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.

Going ahead to step 12:
The number 23 fits into 210 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 28602.521739
Subtracting 207 from 210 leaves us 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.

On to step 13:
30 divided by 23 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 28602.5217391
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.

Step 14:
When dividing 70 by 23, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 28602.52173913
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.

Our division results in 28602.52173913 with a remaining 1e-09.
