We look at the division of 772518 by 19 
The aim is to understand the frequency of 19 in 772518.

Let's proceed to step 1:
If we divide 7 by 19, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 19

Moving on to step 2:
77 divided by 19 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 76 from 77, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 19

Step 3:
19 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 40.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 19

On to step 4:
When dividing 125 by 19, we get 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 406.0
Subtracting 114 from 125 leaves us with 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 19

Step 5:
19 can be fit into 111 5 times, resulting in a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 4065.0
Deduct 95 from 111 and we're left with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 19

Going ahead to step 6:
When dividing 168 by 19, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 40658.0
If we take 152 away from 168, we end up 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.

Let's proceed to step 7:
160 divided by 19 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 40658.8
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
If we divide 80 by 19, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 40658.84
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 19, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 40658.842
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.

On to step 10:
20 divided by 19 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 40658.8421
The remainder is 1 after subtracting 19 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
If we divide 10 by 19, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 40658.8421
Deduct 0 from 10 and we're left 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.

Going ahead to step 12:
100 divided by 19 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 40658.842105
Deduct 95 from 100 and we're left 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.

Step 13:
19 goes into 50 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 40658.8421052
Subtracting 38 from 50 leaves us 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.

Let's proceed to step 14:
When dividing 120 by 19, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 40658.84210526
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 40658.84210526, with a leftover of 6e-09.
