We look at the division of 999278 by 19 
The aim is to understand the frequency of 19 in 999278.

Step 1:
When dividing 9 by 19, we get 0 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.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 19

Step 2:
The number 19 fits into 99 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 95 from 99, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 19

Moving on to step 3:
49 divided by 19 is 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 52.0
The remainder is 11 after subtracting 38 from 49.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 19

Advancing to step 4:
When dividing 112 by 19, we get 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 525.0
If we take 95 away from 112, we end up with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 19

Step 5:
177 divided by 19 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 5259.0
If we subtract 171 from 177, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 19

Step 6:
68 divided by 19 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 52593.0
Subtract 57 from 68 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.

Step 7:
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: 52593.5
The remainder is 15 after subtracting 95 from 110.
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 8:
150 divided by 19 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 52593.57
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
19 can be fit into 170 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 52593.578
If we take 152 away from 170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 52593.5789
Subtracting 171 from 180 leaves us 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.

Moving on to step 11:
When dividing 90 by 19, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 52593.57894
If we take 76 away from 90, we end up 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.

Step 12:
When dividing 140 by 19, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 52593.578947
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.

On to step 13:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 52593.5789473
If we take 57 away from 70, we end up 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.

Going ahead to step 14:
19 goes into 130 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 52593.57894736
Deduct 114 from 130 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 52593.57894736 with a remainder of 1.6e-08.
