We look at the division of 676137 by 15 
The aim is to understand the frequency of 15 in 676137.

Advancing to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 15

Advancing to step 2:
If we divide 67 by 15, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 60 from 67 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 15

On to step 3:
76 divided by 15 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we take 75 away from 76, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 15

Moving on to step 4:
If we divide 11 by 15, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 450.0
Subtract 0 from 11 to get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 15

Moving on to step 5:
15 can be fit into 113 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 4507.0
The remainder is 8 after subtracting 105 from 113.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 15

Step 6:
The number 15 fits into 87 5 times, leaving a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 45075.0
Deduct 75 from 87 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
If we divide 120 by 15, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 45075.8
Subtracting 120 from 120 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45075.8
Subtract 0 from 0 to 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 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45075.8
Subtract 0 from 0 to 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.

In conclusion, the division gives 45075.8 with a balance of 0.0.
