We look at the division of 236857 by 23 
We're looking to find how many times 23 goes into 236857.

On to step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 23

Step 2:
The number 23 fits into 23 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 23 from 23 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 23

Step 3:
23 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 23

Moving on to step 4:
The number 23 fits into 68 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 22 after subtracting 46 from 68.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 23

Advancing to step 5:
When dividing 225 by 23, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 1029.0
Subtracting 207 from 225 leaves us with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 23

Moving on to step 6:
187 divided by 23 is 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 10298.0
If we take 184 away from 187, we end up 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.

Advancing to step 7:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 10298.1
If we take 23 away from 30, we end up 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.

Going ahead to step 8:
23 goes into 70 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 10298.13
Subtracting 69 from 70 leaves us 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.

Going ahead to step 9:
When dividing 10 by 23, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10298.13
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.

Let's proceed to step 10:
If we divide 100 by 23, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 10298.1304
If we take 92 away from 100, we end up with 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 11:
80 divided by 23 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 10298.13043
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.

On to step 12:
When dividing 110 by 23, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 10298.130434
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.

Moving on to step 13:
When dividing 180 by 23, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 10298.1304347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 10298.13043478
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.

After the division, we end up with 10298.13043478 and a remainder of 6e-09.
