We look at the division of 587066 by 19 
The aim is to understand the frequency of 19 in 587066.

Moving on to step 1:
When dividing 5 by 19, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 19

Moving on to step 2:
58 divided by 19 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 57 from 58 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 19

Let's proceed to step 3:
The number 19 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 19

Let's proceed to step 4:
When dividing 170 by 19, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 308.0
Subtracting 152 from 170 leaves us with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 19

Let's proceed to step 5:
19 goes into 186 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 3089.0
Subtracting 171 from 186 leaves us with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 19

Let's proceed to step 6:
When dividing 156 by 19, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 30898.0
The remainder is 4 after subtracting 152 from 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
40 divided by 19 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 30898.2
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 19, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 30898.21
Deduct 19 from 20 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
10 divided by 19 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 30898.21
Subtract 0 from 10 to get 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 10:
When dividing 100 by 19, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 30898.2105
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.

Advancing to step 11:
19 goes into 50 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 30898.21052
If we take 38 away from 50, we end up 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.

Advancing to step 12:
When dividing 120 by 19, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 30898.210526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
19 goes into 60 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 30898.2105263
If we take 57 away from 60, 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 14:
If we divide 30 by 19, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 30898.21052631
If we take 19 away from 30, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 30898.21052631, with a leftover of 1.1e-08.
