We look at the division of 969491 by 19 
The aim is to understand the frequency of 19 in 969491.

On to step 1:
19 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 19

Advancing to step 2:
19 goes into 96 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 95 from 96 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 19

On to step 3:
19 goes into 19 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 19 from 19, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 19

On to step 4:
4 divided by 19 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 510.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 19

On to step 5:
If we divide 49 by 19, we get 2 and a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 5102.0
Subtract 38 from 49 to get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 19

Let's proceed to step 6:
The number 19 fits into 111 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 51025.0
Subtract 95 from 111 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 51025.8
The remainder is 8 after subtracting 152 from 160.
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 8:
If we divide 80 by 19, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 51025.84
If we take 76 away from 80, 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.

Going ahead to step 9:
If we divide 40 by 19, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 51025.842
Subtract 38 from 40 to 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:
19 goes into 20 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 51025.8421
The remainder is 1 after subtracting 19 from 20.
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 11:
If we divide 10 by 19, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 51025.8421
If we take 0 away from 10, we end up 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.

Moving on to step 12:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 51025.842105
Subtracting 95 from 100 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 13:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 51025.8421052
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.

Moving on to step 14:
120 divided by 19 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 51025.84210526
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 51025.84210526, with a leftover of 6e-09.
