345339 divided by 23 
We want to figure out the number of times 345339 can be divided 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
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 23

Moving on to step 2:
23 can be fit into 34 1 times, resulting in a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 23 from 34 leaves us with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 23

Moving on to step 3:
When dividing 115 by 23, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 115 away from 115, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 23

Going ahead to step 4:
3 divided by 23 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtract 0 from 3 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 23

Step 5:
The number 23 fits into 33 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1501.0
Deduct 23 from 33 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 23

Let's proceed to step 6:
23 goes into 109 4 times with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 15014.0
Subtracting 92 from 109 leaves us with 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 7:
170 divided by 23 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 15014.7
If we take 161 away from 170, 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 8:
90 divided by 23 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 15014.73
Subtracting 69 from 90 leaves us 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.

Going ahead to step 9:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 15014.739
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.

Going ahead to step 10:
If we divide 30 by 23, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 15014.7391
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.

Step 11:
When dividing 70 by 23, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 15014.73913
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.

Going ahead to step 12:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 15014.73913
If we subtract 0 from 10, we 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.

Advancing to step 13:
The number 23 fits into 100 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 15014.7391304
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 15014.73913043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 15014.73913043, and the remainder is 1.1e-08.
