We're dividing 765767 by 15 
The aim is to understand the frequency of 15 in 765767.

Moving on to step 1:
15 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 15

Let's proceed to step 2:
76 divided by 15 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 75 from 76 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 15

Step 3:
15 divided by 15 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 51.0
If we take 15 away from 15, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 15

Moving on to step 4:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 510.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 15

Step 5:
15 can be fit into 76 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 5105.0
If we take 75 away from 76, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 15

Moving on to step 6:
15 can be fit into 17 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 51051.0
Subtract 15 from 17 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 15 fits into 20 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 51051.1
Subtract 15 from 20 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 51051.13
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 51051.133
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 51051.133 with a balance of 0.0005.
