We look at the division of 555764 by 19 
The aim is to understand the frequency of 19 in 555764.

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
If we subtract 0 from 5, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 19

Moving on to step 2:
19 goes into 55 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 38 from 55, we get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 19

Going ahead to step 3:
19 goes into 175 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 171 from 175, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 19

Advancing to step 4:
19 goes into 47 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 292.0
Subtracting 38 from 47 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 19

Moving on to step 5:
If we divide 96 by 19, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 2925.0
The remainder is 1 after subtracting 95 from 96.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 19

Going ahead to step 6:
The number 19 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 29250.0
If we take 0 away from 14, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
19 goes into 140 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 29250.7
If we take 133 away from 140, we end up with 7.
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 8:
When dividing 70 by 19, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 29250.73
Deduct 57 from 70 and we're left 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.

On to step 9:
19 goes into 130 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 29250.736
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 10:
If we divide 160 by 19, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 29250.7368
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.

Step 11:
80 divided by 19 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 29250.73684
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.

Let's proceed to step 12:
19 can be fit into 40 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 29250.736842
Subtracting 38 from 40 leaves us 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.

Step 13:
If we divide 20 by 19, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 29250.7368421
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.

On to step 14:
If we divide 10 by 19, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 29250.7368421
Subtracting 0 from 10 leaves us 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.

The final outcome is 29250.7368421, with a leftover of 1e-08.
