We're dividing 669775 by 64 
The aim is to understand the frequency of 64 in 669775.

Advancing to step 1:
64 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 64

Moving on to step 2:
64 can be fit into 66 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 64 from 66 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 64

Step 3:
64 can be fit into 29 0 times, resulting in a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 29 to get 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 64

Let's proceed to step 4:
If we divide 297 by 64, we get 4 and a remainder of 41.
The next digit of our result is 4. 
Result so far: 104.0
If we take 256 away from 297, we end up with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 64

Going ahead to step 5:
64 goes into 417 6 times with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 1046.0
Deduct 384 from 417 and we're left with 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 64

Advancing to step 6:
When dividing 335 by 64, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 10465.0
If we take 320 away from 335, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
The number 64 fits into 150 2 times, leaving a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 10465.2
If we take 128 away from 150, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
64 can be fit into 220 3 times, resulting in a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 10465.23
Subtracting 192 from 220 leaves us 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.

Advancing to step 9:
64 can be fit into 280 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 10465.234
Deduct 256 from 280 and we're left 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.

On to step 10:
If we divide 240 by 64, we get 3 and a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 10465.2343
If we take 192 away from 240, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
480 divided by 64 is 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 10465.23437
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.

Step 12:
320 divided by 64 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10465.234375
Deduct 320 from 320 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.

Step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10465.234375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
64 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: 10465.234375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10465.234375 and a remainder of 0.0.
