965409 divided by 19 
The aim is to understand the frequency of 19 in 965409.

Step 1:
When dividing 9 by 19, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 19

Advancing to step 2:
19 can be fit into 96 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 95 away from 96, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 19

Let's proceed to step 3:
19 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 15 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 19

Moving on to step 4:
19 can be fit into 154 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 508.0
Deduct 152 from 154 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 19

On to step 5:
19 can be fit into 20 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 5081.0
The remainder is 1 after subtracting 19 from 20.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 19

Going ahead to step 6:
If we divide 19 by 19, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 50811.0
Deduct 19 from 19 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 19, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 50811.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 19, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50811.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 50811.0 and a remainder of 0.0.
