We divide 391562 by 13
The aim is to understand the frequency of 13 in 391562.

On to step 1:
If we divide 3 by 13, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 13

Moving on to step 2:
13 goes into 39 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 0 after subtracting 39 from 39.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 13

Going ahead to step 3:
The number 13 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 13

Let's proceed to step 4:
When dividing 15 by 13, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 301.0
Deduct 13 from 15 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 13

Advancing to step 5:
13 can be fit into 26 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 3012.0
Subtracting 26 from 26 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 13

Advancing to step 6:
If we divide 2 by 13, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 30120.0
If we subtract 0 from 2, we get 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 7:
When dividing 20 by 13, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 30120.1
If we take 13 away from 20, we end up 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.

Going ahead to step 8:
When dividing 70 by 13, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 30120.15
If we take 65 away from 70, we end up 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.

Let's proceed to step 9:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 30120.153
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.

On to step 10:
The number 13 fits into 110 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 30120.1538
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.

Step 11:
60 divided by 13 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 30120.15384
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 13, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 30120.153846
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
When dividing 20 by 13, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 30120.1538461
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.

On to step 14:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 30120.15384615
If we take 65 away from 70, we end up 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.

In conclusion, the division gives 30120.15384615 with a balance of 5e-09.
