We look at the division of 130806 by 19 
The aim is to understand the frequency of 19 in 130806.

Going ahead to step 1:
19 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 19

On to step 2:
19 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 19

On to step 3:
19 goes into 130 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 114 from 130 and we're left with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 19

Moving on to step 4:
When dividing 168 by 19, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
If we take 152 away from 168, we end up with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 19

Going ahead to step 5:
If we divide 160 by 19, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 688.0
If we subtract 152 from 160, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 19

Going ahead to step 6:
19 can be fit into 86 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 6884.0
Subtract 76 from 86 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 19 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6884.5
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.

Advancing to step 8:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 6884.52
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
19 can be fit into 120 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6884.526
Subtracting 114 from 120 leaves us 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.

Let's proceed to step 10:
19 can be fit into 60 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6884.5263
Subtract 57 from 60 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.

Going ahead to step 11:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 6884.52631
Subtract 19 from 30 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
When dividing 110 by 19, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6884.526315
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.

Moving on to step 13:
150 divided by 19 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 6884.5263157
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.

On to step 14:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 6884.52631578
Deduct 152 from 170 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 6884.52631578, and the remainder is 1.8e-08.
