We look at the division of 189423 by 23 
We're looking to find how many times 23 goes into 189423.

On to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Moving on to step 2:
The number 23 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 23

Step 3:
189 divided by 23 is 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 5 after subtracting 184 from 189.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 23

Step 4:
When dividing 54 by 23, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we subtract 46 from 54, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 23

Let's proceed to step 5:
23 goes into 82 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 823.0
If we take 69 away from 82, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 23

Going ahead to step 6:
When dividing 133 by 23, we get 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 8235.0
The remainder is 18 after subtracting 115 from 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
23 goes into 180 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 8235.7
Subtracting 161 from 180 leaves us 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.

Let's proceed to step 8:
If we divide 190 by 23, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8235.78
If we take 184 away from 190, we end up with 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 9:
60 divided by 23 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 8235.782
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
140 divided by 23 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 8235.7826
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
The number 23 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8235.7826
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.

Let's proceed to step 12:
200 divided by 23 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8235.782608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
If we divide 160 by 23, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 8235.7826086
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
When dividing 220 by 23, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 8235.78260869
Subtracting 207 from 220 leaves us 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.

After the division, we end up with 8235.78260869 and a remainder of 1.3e-08.
