We divide 339790 by 13
The aim is to understand the frequency of 13 in 339790.

Advancing to step 1:
13 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 13

Step 2:
33 divided by 13 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 26 from 33 leaves us with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 13

On to step 3:
79 divided by 13 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 1 after subtracting 78 from 79.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 13

Going ahead to step 4:
13 can be fit into 17 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
Subtracting 13 from 17 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 13

Going ahead to step 5:
The number 13 fits into 49 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 2613.0
Deduct 39 from 49 and we're left with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 13

Moving on to step 6:
If we divide 100 by 13, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 26137.0
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.

Going ahead to step 7:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 26137.6
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.

Step 8:
120 divided by 13 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 26137.69
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.

Advancing to step 9:
If we divide 30 by 13, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 26137.692
Subtract 26 from 30 to 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.

Let's proceed to step 10:
When dividing 40 by 13, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 26137.6923
The remainder is 1 after subtracting 39 from 40.
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 11:
13 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 26137.6923
Deduct 0 from 10 and we're left 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.

Let's proceed to step 12:
When dividing 100 by 13, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 26137.692307
Deduct 91 from 100 and we're left 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 13:
If we divide 90 by 13, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 26137.6923076
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.

Step 14:
120 divided by 13 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 26137.69230769
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.

In conclusion, the division gives 26137.69230769 with a balance of 3e-09.
