We look at the division of 76521 by 69 
The aim is to understand the frequency of 69 in 76521.

Going ahead to step 1:
The number 69 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 69

Going ahead to step 2:
If we divide 76 by 69, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 69 from 76, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 69

On to step 3:
If we divide 75 by 69, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 69 from 75 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 69

Going ahead to step 4:
When dividing 62 by 69, we get 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtracting 0 from 62 leaves us with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 69

Step 5:
If we divide 621 by 69, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1109.0
If we subtract 621 from 621, we get 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 6:
If we divide 0 by 69, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1109.0
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.

Let's proceed to step 7:
69 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1109.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1109.0, with a leftover of 0.0.
