Let's divide 258143 by 23
Our goal is to divide 258143 by 23.

Going ahead to step 1:
23 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 23

Step 2:
23 goes into 25 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 23 from 25, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 23

Let's proceed to step 3:
When dividing 28 by 23, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 5 after subtracting 23 from 28.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 23

Moving on to step 4:
51 divided by 23 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 112.0
The remainder is 5 after subtracting 46 from 51.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 23

Moving on to step 5:
When dividing 54 by 23, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1122.0
Subtracting 46 from 54 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 23

Advancing to step 6:
83 divided by 23 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 11223.0
Deduct 69 from 83 and we're left 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.

Let's proceed to step 7:
The number 23 fits into 140 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 11223.6
Subtract 138 from 140 to 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.

Let's proceed to step 8:
20 divided by 23 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11223.6
If we take 0 away from 20, we end up 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.

Going ahead to step 9:
When dividing 200 by 23, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 11223.608
If we take 184 away from 200, we end up 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.

On to step 10:
If we divide 160 by 23, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 11223.6086
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
220 divided by 23 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 11223.60869
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
130 divided by 23 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 11223.608695
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11223.6086956
If we subtract 138 from 150, 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 14:
If we divide 120 by 23, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 11223.60869565
Subtracting 115 from 120 leaves us 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.

After the division, we end up with 11223.60869565 and a remainder of 5e-09.
