We look at the division of 190493 by 13 
The aim is to understand the frequency of 13 in 190493.

Let's proceed to step 1:
If we divide 1 by 13, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 13

On to step 2:
19 divided by 13 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 13 from 19, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 13

Moving on to step 3:
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: 14.0
If we take 52 away from 60, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 13

Advancing to step 4:
The number 13 fits into 84 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 146.0
If we subtract 78 from 84, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 13

Step 5:
13 goes into 69 5 times with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 1465.0
Deduct 65 from 69 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 13

Moving on to step 6:
When dividing 43 by 13, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 14653.0
Subtract 39 from 43 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.

On to step 7:
If we divide 40 by 13, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 14653.3
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.

Advancing to step 8:
When dividing 10 by 13, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 14653.3
The remainder is 10 after subtracting 0 from 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 9:
When dividing 100 by 13, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 14653.307
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
13 goes into 90 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 14653.3076
Subtract 78 from 90 to 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.

Going ahead to step 11:
120 divided by 13 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 14653.30769
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.

Advancing to step 12:
30 divided by 13 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 14653.307692
If we take 26 away from 30, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
40 divided by 13 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 14653.3076923
If we take 39 away from 40, we end up 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.

On to step 14:
10 divided by 13 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 14653.3076923
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.

After the division, we end up with 14653.3076923 and a remainder of 1e-08.
