We look at the division of 519936 by 64 
The aim is to understand the frequency of 64 in 519936.

Going ahead to step 1:
When dividing 5 by 64, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 64

Let's proceed to step 2:
The number 64 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 64

Let's proceed to step 3:
If we divide 519 by 64, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 512 from 519 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 64

Step 4:
If we divide 79 by 64, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we subtract 64 from 79, we get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 64

Going ahead to step 5:
The number 64 fits into 153 2 times, leaving a remainder of 25.
The next digit of our result is 2. 
Result so far: 812.0
Subtract 128 from 153 to get 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 64

Let's proceed to step 6:
64 can be fit into 256 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 8124.0
Subtract 256 from 256 to 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 7:
If we divide 0 by 64, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8124.0
If we take 0 away from 0, 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.

Advancing to step 8:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8124.0
If we take 0 away from 0, 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.

The quotient of the division is 8124.0, and the remainder is 0.0.
