We look at the division of 262512 by 19 
The aim is to understand the frequency of 19 in 262512.

Let's proceed to step 1:
If we divide 2 by 19, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 19

Step 2:
When dividing 26 by 19, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 19 away from 26, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 19

Moving on to step 3:
If we divide 72 by 19, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 15 after subtracting 57 from 72.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 19

Moving on to step 4:
When dividing 155 by 19, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 138.0
Subtract 152 from 155 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 19

Step 5:
31 divided by 19 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1381.0
If we subtract 19 from 31, we get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 19

Moving on to step 6:
19 can be fit into 122 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 13816.0
If we take 114 away from 122, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
The number 19 fits into 80 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 13816.4
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 19 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 13816.42
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
20 divided by 19 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 13816.421
If we subtract 19 from 20, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
19 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 13816.421
If we take 0 away from 10, we end up 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.

Step 11:
If we divide 100 by 19, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 13816.42105
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.

On to step 12:
19 can be fit into 50 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 13816.421052
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 13:
The number 19 fits into 120 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 13816.4210526
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
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: 13816.42105263
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 13816.42105263 with a remaining 3e-09.
