We're dividing 396220 by 19 
The aim is to understand the frequency of 19 in 396220.

On to step 1:
When dividing 3 by 19, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 19

Going ahead to step 2:
19 can be fit into 39 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 38 from 39, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 19

Going ahead to step 3:
19 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 16, we get 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 19

Going ahead to step 4:
When dividing 162 by 19, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
Deduct 152 from 162 and we're left with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 19

Advancing to step 5:
If we divide 102 by 19, we get 5 and a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 2085.0
The remainder is 7 after subtracting 95 from 102.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 19

Let's proceed to step 6:
The number 19 fits into 70 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 20853.0
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 19 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 20853.6
Subtract 114 from 130 to 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 8:
19 can be fit into 160 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 20853.68
If we take 152 away from 160, 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 9:
If we divide 80 by 19, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 20853.684
Subtract 76 from 80 to 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.

Moving on to step 10:
If we divide 40 by 19, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 20853.6842
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
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: 20853.68421
Deduct 19 from 20 and we're left 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.

Advancing to step 12:
The number 19 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 20853.68421
The remainder is 10 after subtracting 0 from 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 13:
19 goes into 100 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 20853.6842105
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 14:
If we divide 50 by 19, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 20853.68421052
If we take 38 away from 50, we end up 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.

In conclusion, the division gives 20853.68421052 with a balance of 1.2e-08.
