806210 ÷ 19 
The aim is to understand the frequency of 19 in 806210.

Going ahead to step 1:
19 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 19

Advancing to step 2:
80 divided by 19 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 76 from 80 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 19

Step 3:
19 can be fit into 46 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 38 from 46, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 19

Let's proceed to step 4:
82 divided by 19 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 424.0
If we subtract 76 from 82, we get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 19

Moving on to step 5:
The number 19 fits into 61 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 4243.0
Subtracting 57 from 61 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 19

Advancing to step 6:
When dividing 40 by 19, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 42432.0
If we subtract 38 from 40, we 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.

On to step 7:
The number 19 fits into 20 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 42432.1
Subtracting 19 from 20 leaves us with 1.
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 8:
If we divide 10 by 19, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 42432.1
Subtracting 0 from 10 leaves us 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.

On to step 9:
When dividing 100 by 19, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 42432.105
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.

Step 10:
19 goes into 50 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 42432.1052
Subtract 38 from 50 to 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.

Step 11:
19 goes into 120 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 42432.10526
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 12:
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: 42432.105263
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.

Let's proceed to step 13:
19 goes into 30 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 42432.1052631
Subtracting 19 from 30 leaves us 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 14:
19 goes into 110 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 42432.10526315
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 42432.10526315, and the remainder is 1.5e-08.
