8915 ÷ 64 
The aim is to understand the frequency of 64 in 8915.

Going ahead to step 1:
8 divided by 64 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 64

Step 2:
The number 64 fits into 89 1 times, leaving a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 64 from 89 to get 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 64

Advancing to step 3:
251 divided by 64 is 3 with a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 192 away from 251, we end up with 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 64

On to step 4:
The number 64 fits into 595 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtracting 576 from 595 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 5:
64 goes into 190 2 times with a remainder of 62.
The next digit of our result is 2. 
Result so far: 139.2
Subtracting 128 from 190 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 6:
The number 64 fits into 620 9 times, leaving a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 139.29
Subtract 576 from 620 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
440 divided by 64 is 6 with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 139.296
Subtracting 384 from 440 leaves us 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.

Going ahead to step 8:
64 goes into 560 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 139.2968
The remainder is 48 after subtracting 512 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
480 divided by 64 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 139.29687
If we take 448 away from 480, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 139.296875
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 139.296875
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.

Let's proceed to step 12:
If we divide 0 by 64, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 139.296875
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.

The final outcome is 139.296875, with a leftover of 0.0.
