397539 divided by 13 
We want to divide 397539 by 13.

Let's proceed to step 1:
13 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 13

Step 2:
39 divided by 13 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 39 from 39 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 13

Let's proceed to step 3:
7 divided by 13 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 30.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 13

Step 4:
13 can be fit into 75 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 305.0
If we take 65 away from 75, we end up with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 13

Let's proceed to step 5:
13 can be fit into 103 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 3057.0
The remainder is 12 after subtracting 91 from 103.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 13

On to step 6:
When dividing 129 by 13, we get 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 30579.0
If we subtract 117 from 129, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
The number 13 fits into 120 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 30579.9
If we subtract 117 from 120, we 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 8:
30 divided by 13 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 30579.92
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 13, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 30579.923
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

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: 30579.923
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.

Moving on to step 11:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 30579.92307
The remainder is 9 after subtracting 91 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
The number 13 fits into 90 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 30579.923076
Deduct 78 from 90 and we're left 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.

On to step 13:
13 can be fit into 120 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 30579.9230769
Subtracting 117 from 120 leaves us 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.

Advancing to step 14:
30 divided by 13 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 30579.92307692
If we subtract 26 from 30, we get 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 30579.92307692 and a remainder of 4e-09.
