305242 divided by 23 
Our goal is to divide 305242 by 23.

Step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 23

Moving on to step 2:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 23 away from 30, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 23

Advancing to step 3:
If we divide 75 by 23, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 69 away from 75, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 23

Advancing to step 4:
23 can be fit into 62 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
Subtracting 46 from 62 leaves us with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 23

Advancing to step 5:
The number 23 fits into 164 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 1327.0
If we take 161 away from 164, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 23

Let's proceed to step 6:
32 divided by 23 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 13271.0
If we take 23 away from 32, we end up 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.

Moving on to step 7:
90 divided by 23 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 13271.3
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 13271.39
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 23 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 13271.391
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 13271.3913
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 11:
If we divide 10 by 23, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13271.3913
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.

Advancing to step 12:
23 goes into 100 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 13271.391304
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.

On to step 13:
80 divided by 23 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13271.3913043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 13271.39130434
Subtract 92 from 110 to 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.

The final result is 13271.39130434 with a remainder of 1.8e-08.
