767513 ÷ 15 
The aim is to understand the frequency of 15 in 767513.

Moving on to step 1:
7 divided by 15 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 15

Advancing to step 2:
76 divided by 15 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 75 away from 76, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 15

Step 3:
The number 15 fits into 17 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 15 from 17, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 15

Step 4:
If we divide 25 by 15, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 511.0
If we take 15 away from 25, we end up with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 15

Moving on to step 5:
When dividing 101 by 15, we get 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 5116.0
The remainder is 11 after subtracting 90 from 101.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 15

Let's proceed to step 6:
If we divide 113 by 15, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 51167.0
The remainder is 8 after subtracting 105 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
When dividing 80 by 15, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 51167.5
Subtract 75 from 80 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.

Let's proceed to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 51167.53
Deduct 45 from 50 and we're left 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.

Moving 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: 51167.533
If we subtract 45 from 50, we 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.

In conclusion, the division gives 51167.533 with a balance of 0.0005.
