We look at the division of 86504915 by 10 
The aim is to understand the frequency of 10 in 86504915.

Step 1:
10 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 10

Let's proceed to step 2:
If we divide 86 by 10, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 80 from 86 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 10

Step 3:
65 divided by 10 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 60 from 65, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 10

Step 4:
50 divided by 10 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 865.0
The remainder is 0 after subtracting 50 from 50.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 10

On to step 5:
10 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 8650.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 10

Going ahead to step 6:
10 can be fit into 49 4 times, resulting in a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 86504.0
Subtracting 40 from 49 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 10

Going ahead to step 7:
91 divided by 10 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 865049.0
If we take 90 away from 91, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 10

Let's proceed to step 8:
15 divided by 10 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 8650491.0
The remainder is 5 after subtracting 10 from 15.
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:
50 divided by 10 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8650491.5
Deduct 50 from 50 and we're left 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.

Moving on to step 10:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8650491.5
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.

Moving on to step 11:
10 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8650491.5
Subtracting 0 from 0 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.

In conclusion, the division gives 8650491.5 with a balance of 0.0.
