We look at the division of 802884 by 19 
The aim is to understand the frequency of 19 in 802884.

Let's proceed to step 1:
19 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 19

Step 2:
19 goes into 80 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 4 after subtracting 76 from 80.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 19

Advancing to step 3:
The number 19 fits into 42 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we subtract 38 from 42, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 19

On to step 4:
19 can be fit into 48 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 422.0
Subtract 38 from 48 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 19

Moving on to step 5:
19 can be fit into 108 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 4225.0
If we subtract 95 from 108, we get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 19

On to step 6:
134 divided by 19 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 42257.0
Subtract 133 from 134 to get 1.
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 7:
The number 19 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 42257.0
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.

On to step 8:
19 goes into 100 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 42257.05
If we subtract 95 from 100, we get 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:
If we divide 50 by 19, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 42257.052
Subtracting 38 from 50 leaves us 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 10:
When dividing 120 by 19, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 42257.0526
Deduct 114 from 120 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:
When dividing 60 by 19, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 42257.05263
If we subtract 57 from 60, 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.

Let's proceed to step 12:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 42257.052631
If we take 19 away from 30, we end up 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.

On to step 13:
If we divide 110 by 19, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 42257.0526315
If we subtract 95 from 110, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
If we divide 150 by 19, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 42257.05263157
Deduct 133 from 150 and we're left 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.

The final outcome is 42257.05263157, with a leftover of 1.7e-08.
