We look at the division of 821812 by 69 
The aim is to understand the frequency of 69 in 821812.

Going ahead to step 1:
When dividing 8 by 69, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 69

Let's proceed to step 2:
69 can be fit into 82 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 13 after subtracting 69 from 82.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 69

Step 3:
The number 69 fits into 131 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 69 from 131 and we're left with 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 69

Going ahead to step 4:
The number 69 fits into 628 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Subtracting 621 from 628 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 69

Advancing to step 5:
69 can be fit into 71 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1191.0
Subtracting 69 from 71 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 69

Step 6:
69 goes into 22 0 times with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 11910.0
The remainder is 22 after subtracting 0 from 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
When dividing 220 by 69, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 11910.3
If we take 207 away from 220, we end up with 13.
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:
The number 69 fits into 130 1 times, leaving a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 11910.31
The remainder is 61 after subtracting 69 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
610 divided by 69 is 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 11910.318
If we subtract 552 from 610, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
When dividing 580 by 69, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 11910.3188
If we subtract 552 from 580, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 11910.3188 with a remainder of 0.00028.
