We look at the division of 616458 by 19 
The aim is to understand the frequency of 19 in 616458.

On to step 1:
When dividing 6 by 19, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 19

Advancing to step 2:
61 divided by 19 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 57 away from 61, we end up with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 19

Step 3:
The number 19 fits into 46 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we subtract 38 from 46, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 19

Moving on to step 4:
The number 19 fits into 84 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 324.0
Subtracting 76 from 84 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 19

On to step 5:
If we divide 85 by 19, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 3244.0
The remainder is 9 after subtracting 76 from 85.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 19

Going ahead to step 6:
98 divided by 19 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 32445.0
If we take 95 away from 98, we end up 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 7:
If we divide 30 by 19, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 32445.1
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.

Let's proceed to step 8:
19 goes into 110 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 32445.15
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 9:
If we divide 150 by 19, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 32445.157
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.

Advancing to step 10:
19 can be fit into 170 8 times, resulting in a remainder of 18.
The next digit of our result is 8. 
Result so far: 32445.1578
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.

Step 11:
If we divide 180 by 19, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 32445.15789
If we take 171 away from 180, we end up 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:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 32445.157894
The remainder is 14 after subtracting 76 from 90.
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:
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: 32445.1578947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
If we divide 70 by 19, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 32445.15789473
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.

Our division results in 32445.15789473 with a remaining 1.3e-08.
