We look at the division of 579157 by 19 
The aim is to understand the frequency of 19 in 579157.

Let's proceed to step 1:
19 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 19

Moving on to step 2:
If we divide 57 by 19, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we take 57 away from 57, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 19

On to step 3:
19 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 19

Going ahead to step 4:
The number 19 fits into 91 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 304.0
Deduct 76 from 91 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 19

On to step 5:
19 can be fit into 155 8 times, resulting in a remainder of 3.
The next digit of our result is 8. 
Result so far: 3048.0
If we take 152 away from 155, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 19

Step 6:
19 can be fit into 37 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 30481.0
Subtracting 19 from 37 leaves us 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 7:
When dividing 180 by 19, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 30481.9
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
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: 30481.94
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.

On to step 9:
If we divide 140 by 19, we get 7 and a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 30481.947
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.

Advancing to step 10:
If we divide 70 by 19, we get 3 and a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 30481.9473
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
19 goes into 130 6 times with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 30481.94736
Subtracting 114 from 130 leaves us 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.

Step 12:
When dividing 160 by 19, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 30481.947368
If we subtract 152 from 160, we get 8.
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 13:
19 goes into 80 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 30481.9473684
Deduct 76 from 80 and we're left 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.

Advancing to step 14:
The number 19 fits into 40 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 30481.94736842
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 30481.94736842, with a leftover of 2e-09.
