696398 ÷ 19 
The aim is to understand the frequency of 19 in 696398.

Going ahead to step 1:
19 can be fit into 6 0 times, resulting in 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.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 19

Advancing to step 2:
If we divide 69 by 19, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 57 away from 69, we end up with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 19

Advancing to step 3:
The number 19 fits into 126 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 114 from 126, we get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 19

Going ahead to step 4:
19 can be fit into 123 6 times, resulting in a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 366.0
The remainder is 9 after subtracting 114 from 123.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 19

Let's proceed to step 5:
If we divide 99 by 19, we get 5 and a remainder of 4.
The next digit of our result is 5. 
Result so far: 3665.0
Subtracting 95 from 99 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 19

Let's proceed to step 6:
19 can be fit into 48 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 36652.0
If we subtract 38 from 48, 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.

On to step 7:
When dividing 100 by 19, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 36652.5
The remainder is 5 after subtracting 95 from 100.
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 8:
19 goes into 50 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 36652.52
The remainder is 12 after subtracting 38 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
120 divided by 19 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 36652.526
If we subtract 114 from 120, we 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.

Step 10:
19 goes into 60 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 36652.5263
The remainder is 3 after subtracting 57 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
30 divided by 19 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 36652.52631
If we take 19 away from 30, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
If we divide 110 by 19, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 36652.526315
Deduct 95 from 110 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
19 goes into 150 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 36652.5263157
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
When dividing 170 by 19, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 36652.52631578
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.

The final outcome is 36652.52631578, with a leftover of 1.8e-08.
