We look at the division of 76580511 by 64 
The aim is to understand the frequency of 64 in 76580511.

Step 1:
64 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 64

Advancing to step 2:
If we divide 76 by 64, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 64 away from 76, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 64

Moving on to step 3:
64 goes into 125 1 times with a remainder of 61.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 64 from 125 to get 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 64

On to step 4:
64 can be fit into 618 9 times, resulting in a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 119.0
The remainder is 42 after subtracting 576 from 618.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 64

Going ahead to step 5:
64 goes into 420 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 1196.0
Subtracting 384 from 420 leaves us with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 64

Going ahead to step 6:
365 divided by 64 is 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 11965.0
The remainder is 45 after subtracting 320 from 365.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 64

Advancing to step 7:
64 goes into 451 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 119657.0
If we take 448 away from 451, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 64

Let's proceed to step 8:
If we divide 31 by 64, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 1196570.0
Deduct 0 from 31 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
64 goes into 310 4 times with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 1196570.4
If we take 256 away from 310, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
The number 64 fits into 540 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 1196570.48
Deduct 512 from 540 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
64 can be fit into 280 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 1196570.484
Subtracting 256 from 280 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
If we divide 240 by 64, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1196570.4843
Subtract 192 from 240 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
480 divided by 64 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 1196570.48437
Subtracting 448 from 480 leaves us 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 14:
If we divide 320 by 64, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1196570.484375
If we take 320 away from 320, we end up 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 15:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1196570.484375
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.

Going ahead to step 16:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1196570.484375
Deduct 0 from 0 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.

In conclusion, the division gives 1196570.484375 with a balance of 0.0.
