We look at the division of 868424 by 64 
The aim is to understand the frequency of 64 in 868424.

Advancing to step 1:
When dividing 8 by 64, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 64

Step 2:
86 divided by 64 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 64 from 86, we get 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 64

Step 3:
If we divide 228 by 64, we get 3 and a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 192 from 228 and we're left with 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 64

On to step 4:
364 divided by 64 is 5 with a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we take 320 away from 364, we end up with 44.
Bring next digit (2) of the dividend behind the 44 and repeat the process: 442 / 64

Going ahead to step 5:
The number 64 fits into 442 6 times, leaving a remainder of 58.
The next digit of our result is 6. 
Result so far: 1356.0
The remainder is 58 after subtracting 384 from 442.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 64

Moving on to step 6:
64 goes into 584 9 times with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 13569.0
Subtracting 576 from 584 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
64 can be fit into 80 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 13569.1
Subtract 64 from 80 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
64 goes into 160 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 13569.12
Subtracting 128 from 160 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 9:
64 goes into 320 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 13569.125
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.

Step 10:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13569.125
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.

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: 13569.125
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.

Our division results in 13569.125 with a remaining 0.0.
