Let's divide 624621 by 19
The aim is to understand the frequency of 19 in 624621.

Advancing to step 1:
19 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 19

On to step 2:
19 can be fit into 62 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 57 from 62, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 19

Moving on to step 3:
19 goes into 54 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 38 away from 54, we end up with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 19

Advancing to step 4:
19 goes into 166 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 328.0
Subtracting 152 from 166 leaves us with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 19

Step 5:
When dividing 142 by 19, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 3287.0
The remainder is 9 after subtracting 133 from 142.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 19

Step 6:
The number 19 fits into 91 4 times, leaving a remainder of 15.
The next digit of our result is 4. 
Result so far: 32874.0
If we subtract 76 from 91, 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.

Going ahead to step 7:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 32874.7
If we take 133 away from 150, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
The number 19 fits into 170 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 32874.78
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
19 goes into 180 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 32874.789
Subtract 171 from 180 to get 9.
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 10:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 32874.7894
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.

Let's proceed to step 11:
When dividing 140 by 19, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 32874.78947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
19 can be fit into 70 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 32874.789473
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.

Step 13:
19 goes into 130 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 32874.7894736
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 14:
160 divided by 19 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 32874.78947368
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 32874.78947368 with a remainder of 8e-09.
