309380 divided by 13 
We want to divide 309380 by 13.

On to step 1:
The number 13 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 13

Going ahead to step 2:
13 goes into 30 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 26 from 30, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 13

Let's proceed to step 3:
When dividing 49 by 13, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 39 from 49 and we're left with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 13

Let's proceed to step 4:
The number 13 fits into 103 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 237.0
If we take 91 away from 103, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 13

Moving on to step 5:
The number 13 fits into 128 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 2379.0
If we subtract 117 from 128, we get 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 13

Going ahead to step 6:
110 divided by 13 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 23798.0
If we subtract 104 from 110, we 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.

Step 7:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 23798.4
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.

Going ahead to step 8:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 23798.46
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.

Going ahead to step 9:
If we divide 20 by 13, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 23798.461
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 10:
13 goes into 70 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 23798.4615
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 11:
13 goes into 50 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 23798.46153
If we take 39 away from 50, we end up 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.

Let's proceed to step 12:
When dividing 110 by 13, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 23798.461538
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
If we divide 60 by 13, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 23798.4615384
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.

Moving on to step 14:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 23798.46153846
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.

The final outcome is 23798.46153846, with a leftover of 2e-09.
