479980 divided by 64 
The aim is to understand the frequency of 64 in 479980.

Let's proceed to step 1:
64 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 64

On to step 2:
If we divide 47 by 64, we get 0 and a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 64

Advancing to step 3:
64 goes into 479 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 31 after subtracting 448 from 479.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 64

Moving on to step 4:
If we divide 319 by 64, we get 4 and a remainder of 63.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 256 from 319 to get 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 64

On to step 5:
638 divided by 64 is 9 with a remainder of 62.
Write down 9 as next digit of the result. 
Result so far: 749.0
Subtract 576 from 638 to get 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 64

Advancing to step 6:
64 goes into 620 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 7499.0
Subtract 576 from 620 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
64 can be fit into 440 6 times, resulting in a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 7499.6
The remainder is 56 after subtracting 384 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
64 can be fit into 560 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 7499.68
Deduct 512 from 560 and we're left 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.

Going ahead to step 9:
480 divided by 64 is 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 7499.687
Deduct 448 from 480 and we're left 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 10:
64 goes into 320 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 7499.6875
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.

Advancing to step 11:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7499.6875
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.

Let's proceed to step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7499.6875
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.

The final outcome is 7499.6875, with a leftover of 0.0.
