We look at the division of 195361 by 19 
The aim is to understand the frequency of 19 in 195361.

On to step 1:
19 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 19

Step 2:
The number 19 fits into 19 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 19 from 19, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 19

Let's proceed to step 3:
When dividing 5 by 19, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 19

Going ahead to step 4:
19 goes into 53 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we take 38 away from 53, we end up with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 19

Going ahead to step 5:
19 can be fit into 156 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 1028.0
If we subtract 152 from 156, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 19

On to step 6:
When dividing 41 by 19, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 10282.0
Subtract 38 from 41 to 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.

On to step 7:
The number 19 fits into 30 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 10282.1
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.

Moving on to step 8:
The number 19 fits into 110 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 10282.15
If we subtract 95 from 110, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
The number 19 fits into 150 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 10282.157
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 10282.1578
Subtract 152 from 170 to 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.

Moving on to step 11:
19 goes into 180 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 10282.15789
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 12:
90 divided by 19 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 10282.157894
The remainder is 14 after subtracting 76 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
When dividing 140 by 19, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 10282.1578947
If we subtract 133 from 140, we 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.

Step 14:
19 goes into 70 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 10282.15789473
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.

After the division, we end up with 10282.15789473 and a remainder of 1.3e-08.
