We look at the division of 62158819 by 13 
The aim is to understand the frequency of 13 in 62158819.

Step 1:
When dividing 6 by 13, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 13

Advancing to step 2:
13 goes into 62 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 52 from 62 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 13

Step 3:
13 can be fit into 101 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 91 from 101 and we're left with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 13

Let's proceed to step 4:
The number 13 fits into 105 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 478.0
If we subtract 104 from 105, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 13

Let's proceed to step 5:
If we divide 18 by 13, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 4781.0
If we take 13 away from 18, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 13

Moving on to step 6:
The number 13 fits into 58 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 47814.0
The remainder is 6 after subtracting 52 from 58.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 13

Moving on to step 7:
13 can be fit into 61 4 times, resulting in a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 478144.0
If we subtract 52 from 61, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 13

Step 8:
13 goes into 99 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 4781447.0
If we subtract 91 from 99, 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.

Step 9:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 4781447.6
If we subtract 78 from 80, 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.

Advancing to step 10:
13 goes into 20 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 4781447.61
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.

Advancing to step 11:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 4781447.615
Subtracting 65 from 70 leaves us 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 12:
When dividing 50 by 13, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 4781447.6153
Deduct 39 from 50 and we're left 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.

Advancing to step 13:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 4781447.61538
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
If we divide 60 by 13, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4781447.615384
Subtracting 52 from 60 leaves us 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.

On to step 15:
80 divided by 13 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 4781447.6153846
Deduct 78 from 80 and we're left 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.

Moving on to step 16:
If we divide 20 by 13, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 4781447.61538461
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.

After the division, we end up with 4781447.61538461 and a remainder of 7e-09.
