635575 ÷ 64 
The aim is to understand the frequency of 64 in 635575.

Step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 64

Step 2:
64 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 64

Step 3:
64 can be fit into 635 9 times, resulting in a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 576 from 635, we get 59.
Append the next digit (5) from the dividend to 59 and continue with: 595 / 64

On to step 4:
When dividing 595 by 64, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtract 576 from 595 to get 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 64

Advancing to step 5:
197 divided by 64 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 993.0
The remainder is 5 after subtracting 192 from 197.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 64

Advancing to step 6:
64 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 9930.0
Subtracting 0 from 55 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
If we divide 550 by 64, we get 8 and a remainder of 38.
The next digit of our result is 8. 
Result so far: 9930.8
The remainder is 38 after subtracting 512 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
The number 64 fits into 380 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 9930.85
The remainder is 60 after subtracting 320 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
64 can be fit into 600 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 9930.859
If we subtract 576 from 600, we get 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:
240 divided by 64 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 9930.8593
Subtracting 192 from 240 leaves us 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.

Moving on to step 11:
64 goes into 480 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 9930.85937
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
320 divided by 64 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9930.859375
Subtract 320 from 320 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.

On to step 13:
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: 9930.859375
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.

Moving on to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9930.859375
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.

After the division, we end up with 9930.859375 and a remainder of 0.0.
