We're dividing 815622 by 19 
The aim is to understand the frequency of 19 in 815622.

Step 1:
The number 19 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 19

Going ahead to step 2:
If we divide 81 by 19, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 76 from 81 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 19

On to step 3:
If we divide 55 by 19, we get 2 and a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 38 from 55 to get 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 19

On to step 4:
19 goes into 176 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 429.0
Deduct 171 from 176 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 19

Going ahead to step 5:
19 goes into 52 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 4292.0
If we take 38 away from 52, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 19

Let's proceed to step 6:
142 divided by 19 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 42927.0
The remainder is 9 after subtracting 133 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 19, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 42927.4
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.

Advancing to step 8:
19 goes into 140 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 42927.47
Subtracting 133 from 140 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 42927.473
If we take 57 away from 70, we end up 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.

Moving on to step 10:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 42927.4736
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 42927.47368
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.

Step 12:
19 goes into 80 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 42927.473684
If we take 76 away from 80, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
40 divided by 19 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 42927.4736842
If we take 38 away from 40, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
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: 42927.47368421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 42927.47368421, and the remainder is 1e-09.
