We look at the division of 690315 by 19 
The aim is to understand the frequency of 19 in 690315.

Let's proceed to step 1:
19 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 19

Going ahead to step 2:
19 goes into 69 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 57 from 69, we get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 19

Let's proceed to step 3:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 114 from 120 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 19

Step 4:
When dividing 63 by 19, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 363.0
Deduct 57 from 63 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 19

Advancing to step 5:
If we divide 61 by 19, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3633.0
Subtract 57 from 61 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 19

On to step 6:
19 can be fit into 45 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 36332.0
Subtracting 38 from 45 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.

Moving on to step 7:
70 divided by 19 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 36332.3
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
19 can be fit into 130 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 36332.36
Deduct 114 from 130 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 9:
When dividing 160 by 19, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 36332.368
If we subtract 152 from 160, we 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.

Moving on to step 10:
19 can be fit into 80 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 36332.3684
Subtracting 76 from 80 leaves us 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 11:
40 divided by 19 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 36332.36842
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.

Going ahead to step 12:
If we divide 20 by 19, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 36332.368421
If we take 19 away from 20, 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 13:
19 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 36332.368421
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
When dividing 100 by 19, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 36332.36842105
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.

After the division, we end up with 36332.36842105 and a remainder of 5e-09.
