We're dividing 102423 by 23 
We're looking to find how many times 23 goes into 102423.

Step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 23

Advancing to step 2:
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: 0.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 23

Advancing to step 3:
102 divided by 23 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 92 from 102 and we're left with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 23

Moving on to step 4:
104 divided by 23 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 92 from 104 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 23

Going ahead to step 5:
23 goes into 122 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 445.0
Deduct 115 from 122 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 23

Advancing to step 6:
When dividing 73 by 23, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 4453.0
Subtract 69 from 73 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 23, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 4453.1
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 4453.17
Subtracting 161 from 170 leaves us 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.

Going ahead to step 9:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 4453.173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 10:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 4453.1739
If we take 207 away from 210, 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.

Step 11:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 4453.17391
Deduct 23 from 30 and we're left 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.

Let's proceed to step 12:
23 goes into 70 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 4453.173913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4453.173913
Deduct 0 from 10 and we're left 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.

Going ahead to step 14:
When dividing 100 by 23, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4453.17391304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 4453.17391304 with a balance of 8e-09.
