We're dividing 638682 by 19 
The aim is to understand the frequency of 19 in 638682.

Step 1:
If we divide 6 by 19, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 19

Let's proceed to step 2:
When dividing 63 by 19, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 57 from 63 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 19

Advancing to step 3:
The number 19 fits into 68 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 11 after subtracting 57 from 68.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 19

Let's proceed to step 4:
116 divided by 19 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 336.0
Subtract 114 from 116 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 19

Let's proceed to step 5:
19 can be fit into 28 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 3361.0
The remainder is 9 after subtracting 19 from 28.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 19

Going ahead to step 6:
The number 19 fits into 92 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 33614.0
Deduct 76 from 92 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
When dividing 160 by 19, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 33614.8
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
19 goes into 80 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 33614.84
The remainder is 4 after subtracting 76 from 80.
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 9:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 33614.842
Subtracting 38 from 40 leaves us 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.

On to step 10:
When dividing 20 by 19, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 33614.8421
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.

Moving on to step 11:
19 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 33614.8421
Deduct 0 from 10 and we're left 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.

Step 12:
When dividing 100 by 19, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 33614.842105
If we subtract 95 from 100, we get 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 13:
When dividing 50 by 19, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 33614.8421052
If we subtract 38 from 50, we 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.

Advancing to step 14:
120 divided by 19 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 33614.84210526
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 33614.84210526 and a remainder of 6e-09.
