We look at the division of 993893 by 19 
The aim is to understand the frequency of 19 in 993893.

Moving on to step 1:
19 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 19

Moving on to step 2:
The number 19 fits into 99 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 95 from 99, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 19

Let's proceed to step 3:
19 goes into 43 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
The remainder is 5 after subtracting 38 from 43.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 19

Step 4:
19 goes into 58 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 523.0
If we subtract 57 from 58, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 19

Going ahead to step 5:
19 divided by 19 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 5231.0
If we subtract 19 from 19, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 19

Advancing to step 6:
19 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 52310.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 19, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 52310.1
Subtract 19 from 30 to 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 8:
110 divided by 19 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 52310.15
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 19 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 52310.157
Subtracting 133 from 150 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
170 divided by 19 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 52310.1578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 11:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 52310.15789
Deduct 171 from 180 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.

Going ahead to step 12:
90 divided by 19 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 52310.157894
Subtracting 76 from 90 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
19 goes into 140 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 52310.1578947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
If we divide 70 by 19, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 52310.15789473
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 52310.15789473 and a remainder of 1.3e-08.
