452139 divided by 23 
We want to divide 452139 by 23.

Step 1:
When dividing 4 by 23, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 23

Step 2:
If we divide 45 by 23, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 23 from 45, we get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 23

Advancing to step 3:
222 divided by 23 is 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 207 from 222, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 23

Step 4:
23 can be fit into 151 6 times, resulting in a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
The remainder is 13 after subtracting 138 from 151.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 23

Let's proceed to step 5:
When dividing 133 by 23, we get 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 1965.0
The remainder is 18 after subtracting 115 from 133.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 23

Let's proceed to step 6:
23 goes into 189 8 times with a remainder of 5.
The next digit of our result is 8. 
Result so far: 19658.0
If we subtract 184 from 189, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
23 goes into 50 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 19658.2
If we take 46 away from 50, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 23, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 19658.21
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.

Moving on to step 9:
23 goes into 170 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 19658.217
The remainder is 9 after subtracting 161 from 170.
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 10:
23 goes into 90 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 19658.2173
Deduct 69 from 90 and we're left 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.

Step 11:
210 divided by 23 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19658.21739
Subtract 207 from 210 to get 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 12:
30 divided by 23 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 19658.217391
The remainder is 7 after subtracting 23 from 30.
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 13:
23 goes into 70 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 19658.2173913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 19658.2173913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 19658.2173913 and a remainder of 1e-08.
