We're dividing 508287 by 64 
The aim is to understand the frequency of 64 in 508287.

Advancing to step 1:
The number 64 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 64

Let's proceed to step 2:
64 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 64

On to step 3:
When dividing 508 by 64, we get 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 448 away from 508, we end up with 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 64

Advancing to step 4:
64 goes into 602 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 576 from 602 leaves us with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 64

Moving on to step 5:
64 goes into 268 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 794.0
Deduct 256 from 268 and we're left with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 64

Going ahead to step 6:
127 divided by 64 is 1 with a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 7941.0
If we subtract 64 from 127, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
The number 64 fits into 630 9 times, leaving a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 7941.9
Subtracting 576 from 630 leaves us 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 8:
64 goes into 540 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 7941.98
Subtracting 512 from 540 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:
The number 64 fits into 280 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 7941.984
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.

Let's proceed to step 10:
240 divided by 64 is 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 7941.9843
The remainder is 48 after subtracting 192 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
480 divided by 64 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7941.98437
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.

Let's proceed to step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7941.984375
Subtracting 320 from 320 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.

Going ahead to step 13:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7941.984375
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 14:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7941.984375
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 7941.984375 and a remainder of 0.0.
