We look at the division of 19157927 by 69 
The aim is to understand the frequency of 69 in 19157927.

Advancing to step 1:
If we divide 1 by 69, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 69

Let's proceed to step 2:
19 divided by 69 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 69

Let's proceed to step 3:
69 can be fit into 191 2 times, resulting in a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 138 away from 191, we end up with 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 69

Going ahead to step 4:
If we divide 535 by 69, we get 7 and a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 483 from 535 and we're left with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 69

Let's proceed to step 5:
527 divided by 69 is 7 with a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
Deduct 483 from 527 and we're left with 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 69

Let's proceed to step 6:
449 divided by 69 is 6 with a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 2776.0
Subtract 414 from 449 to get 35.
Grab the next digit (2) from the dividend, add it to 35, then carry on: 352 / 69

Moving on to step 7:
When dividing 352 by 69, we get 5 with a remainder of 7.
The next digit of our result is 5. 
Result so far: 27765.0
The remainder is 7 after subtracting 345 from 352.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 69

Moving on to step 8:
When dividing 77 by 69, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 277651.0
Subtracting 69 from 77 leaves us with 8.
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 9:
69 can be fit into 80 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 277651.1
If we subtract 69 from 80, 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.

Moving on to step 10:
If we divide 110 by 69, we get 1 and a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 277651.11
If we subtract 69 from 110, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 277651.11 with a remaining 0.041.
