We look at the division of 308489 by 13 
We're looking to find how many times 13 goes into 308489.

Advancing to step 1:
3 divided by 13 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 13

Step 2:
30 divided by 13 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 26 from 30 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 13

Advancing to step 3:
13 goes into 48 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 39 from 48 to get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 13

Let's proceed to step 4:
When dividing 94 by 13, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 237.0
Deduct 91 from 94 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 13

On to step 5:
If we divide 38 by 13, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2372.0
Subtracting 26 from 38 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 13

On to step 6:
13 goes into 129 9 times with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 23729.0
Subtracting 117 from 129 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 13 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 23729.9
Subtract 117 from 120 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 8:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 23729.92
Deduct 26 from 30 and we're left 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.

On to step 9:
If we divide 40 by 13, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 23729.923
If we subtract 39 from 40, we 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.

Moving on to step 10:
When dividing 10 by 13, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 23729.923
If we take 0 away from 10, we end up 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.

Moving on to step 11:
When dividing 100 by 13, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 23729.92307
Subtracting 91 from 100 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.

Advancing to step 12:
If we divide 90 by 13, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 23729.923076
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
120 divided by 13 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 23729.9230769
If we take 117 away from 120, 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.

On to step 14:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 23729.92307692
Subtracting 26 from 30 leaves us 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.

After the division, we end up with 23729.92307692 and a remainder of 4e-09.
