807611 divided by 19 
The aim is to understand the frequency of 19 in 807611.

On to step 1:
If we divide 8 by 19, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 19

Moving on to step 2:
19 goes into 80 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 76 from 80 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 19

On to step 3:
When dividing 47 by 19, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 38 away from 47, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 19

Let's proceed to step 4:
When dividing 96 by 19, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 425.0
Subtract 95 from 96 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 19

On to step 5:
If we divide 11 by 19, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 4250.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 19

Advancing to step 6:
19 goes into 111 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 42505.0
If we subtract 95 from 111, 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.

Advancing to step 7:
19 goes into 160 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 42505.8
Deduct 152 from 160 and we're left 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.

Let's proceed to step 8:
When dividing 80 by 19, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 42505.84
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.

Going ahead to step 9:
When dividing 40 by 19, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 42505.842
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 10:
If we divide 20 by 19, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 42505.8421
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.

Let's proceed to step 11:
10 divided by 19 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 42505.8421
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:
When dividing 100 by 19, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 42505.842105
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.

Let's proceed to step 13:
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: 42505.8421052
Deduct 38 from 50 and we're left 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.

Going ahead to step 14:
19 goes into 120 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 42505.84210526
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.

The final result is 42505.84210526 with a remainder of 6e-09.
