23209115 divided by 13 
Our goal is to divide 23209115 by 13.

Step 1:
When dividing 2 by 13, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 13

Step 2:
13 can be fit into 23 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 13 from 23, we get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 13

Moving on to step 3:
102 divided by 13 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 91 from 102 to get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 13

Going ahead to step 4:
When dividing 110 by 13, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 178.0
The remainder is 6 after subtracting 104 from 110.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 13

Let's proceed to step 5:
The number 13 fits into 69 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 1785.0
If we take 65 away from 69, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 13

Step 6:
13 can be fit into 41 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 17853.0
Subtracting 39 from 41 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 13

On to step 7:
The number 13 fits into 21 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 178531.0
Subtract 13 from 21 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 13

Advancing to step 8:
The number 13 fits into 85 6 times, leaving a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 1785316.0
Deduct 78 from 85 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.

Step 9:
70 divided by 13 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 1785316.5
Deduct 65 from 70 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
If we divide 50 by 13, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 1785316.53
If we subtract 39 from 50, 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.

Advancing to step 11:
When dividing 110 by 13, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 1785316.538
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
13 goes into 60 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1785316.5384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
13 goes into 80 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 1785316.53846
Subtracting 78 from 80 leaves us 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.

Moving on to step 14:
When dividing 20 by 13, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1785316.538461
Subtract 13 from 20 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.

Advancing to step 15:
13 goes into 70 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1785316.5384615
Subtract 65 from 70 to 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.

Advancing to step 16:
13 goes into 50 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 1785316.53846153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 1785316.53846153 with a remainder of 1.1e-08.
