629984 ÷ 19 
The aim is to understand the frequency of 19 in 629984.

Moving on to step 1:
19 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in 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

Moving on to step 2:
62 divided by 19 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 57 from 62 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 19

Advancing to step 3:
If we divide 59 by 19, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 57 away from 59, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 19

Step 4:
19 goes into 29 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 331.0
If we subtract 19 from 29, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 19

On to step 5:
The number 19 fits into 108 5 times, leaving a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 3315.0
Subtract 95 from 108 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 19

On to step 6:
If we divide 134 by 19, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 33157.0
If we take 133 away from 134, we end up 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.

Moving on to step 7:
19 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 33157.0
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.

Going ahead to step 8:
100 divided by 19 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33157.05
Deduct 95 from 100 and we're left 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 9:
50 divided by 19 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 33157.052
Subtracting 38 from 50 leaves us 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.

On to step 10:
The number 19 fits into 120 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 33157.0526
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.

Moving on to step 11:
When dividing 60 by 19, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 33157.05263
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
19 goes into 30 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 33157.052631
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
110 divided by 19 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 33157.0526315
Subtract 95 from 110 to 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.

Moving on to step 14:
If we divide 150 by 19, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 33157.05263157
The remainder is 17 after subtracting 133 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 33157.05263157 with a remainder of 1.7e-08.
