We're dividing 766577 by 69 
The aim is to understand the frequency of 69 in 766577.

Let's proceed to step 1:
If we divide 7 by 69, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 69

Step 2:
If we divide 76 by 69, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 69 from 76 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 69

Step 3:
The number 69 fits into 76 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 69 from 76 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 69

Moving on to step 4:
69 can be fit into 75 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
If we subtract 69 from 75, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 69

Moving on to step 5:
When dividing 67 by 69, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 1110.0
Subtract 0 from 67 to get 67.
Append the next digit (7) from the dividend to 67 and continue with: 677 / 69

Advancing to step 6:
The number 69 fits into 677 9 times, leaving a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 11109.0
Deduct 621 from 677 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
69 goes into 560 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 11109.8
Subtracting 552 from 560 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.

Moving on to step 8:
If we divide 80 by 69, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 11109.81
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.

Advancing to step 9:
If we divide 110 by 69, we get 1 and a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 11109.811
If we take 69 away from 110, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 11109.811, with a leftover of 0.0041.
