We look at the division of 36215329 by 19 
The aim is to understand the frequency of 19 in 36215329.

Step 1:
When dividing 3 by 19, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 19

On to step 2:
19 can be fit into 36 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 19 from 36, we get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 19

Moving on to step 3:
172 divided by 19 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 19.0
The remainder is 1 after subtracting 171 from 172.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 19

Let's proceed to step 4:
When dividing 11 by 19, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 19

On to step 5:
19 can be fit into 115 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1906.0
The remainder is 1 after subtracting 114 from 115.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 19

Let's proceed to step 6:
When dividing 13 by 19, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 19060.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 19

Moving on to step 7:
When dividing 132 by 19, we get 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 190606.0
Deduct 114 from 132 and we're left with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 19

Going ahead to step 8:
If we divide 189 by 19, we get 9 and a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1906069.0
If we subtract 171 from 189, we get 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 9:
The number 19 fits into 180 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 1906069.9
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.

On to step 10:
90 divided by 19 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1906069.94
If we take 76 away from 90, 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.

Step 11:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 1906069.947
Subtract 133 from 140 to 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 12:
70 divided by 19 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1906069.9473
Subtracting 57 from 70 leaves us 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.

Going ahead to step 13:
If we divide 130 by 19, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 1906069.94736
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 1906069.947368
Subtract 152 from 160 to 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.

Let's proceed to step 15:
If we divide 80 by 19, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1906069.9473684
Subtracting 76 from 80 leaves us 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.

On to step 16:
If we divide 40 by 19, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 1906069.94736842
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.

In conclusion, the division gives 1906069.94736842 with a balance of 2e-09.
