We look at the division of 906785 by 19 
The aim is to understand the frequency of 19 in 906785.

Going ahead to step 1:
If we divide 9 by 19, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 19

Advancing to step 2:
If we divide 90 by 19, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 14 after subtracting 76 from 90.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 19

Step 3:
19 can be fit into 146 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 47.0
Deduct 133 from 146 and we're left with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 19

Moving on to step 4:
If we divide 137 by 19, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 477.0
If we subtract 133 from 137, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 19

Step 5:
19 goes into 48 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 4772.0
Subtract 38 from 48 to get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 19

Advancing to step 6:
19 goes into 105 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 47725.0
If we take 95 away from 105, 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.

Advancing to step 7:
When dividing 100 by 19, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 47725.5
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.

Moving on to step 8:
The number 19 fits into 50 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 47725.52
If we subtract 38 from 50, we 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.

Let's proceed to step 9:
19 goes into 120 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 47725.526
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.

Moving on to step 10:
The number 19 fits into 60 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 47725.5263
Deduct 57 from 60 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
30 divided by 19 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 47725.52631
If we subtract 19 from 30, we 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 12:
If we divide 110 by 19, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 47725.526315
Subtracting 95 from 110 leaves us 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.

Step 13:
If we divide 150 by 19, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 47725.5263157
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.

Step 14:
The number 19 fits into 170 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 47725.52631578
Deduct 152 from 170 and we're left 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.

After the division, we end up with 47725.52631578 and a remainder of 1.8e-08.
