Let's divide 865408 by 64
The aim is to understand the frequency of 64 in 865408.

Advancing to step 1:
64 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 64

Moving on to step 2:
If we divide 86 by 64, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 64 from 86 leaves us with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 64

Moving on to step 3:
The number 64 fits into 225 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 192 away from 225, we end up with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 64

Moving on to step 4:
The number 64 fits into 334 5 times, leaving a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Deduct 320 from 334 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 64

On to step 5:
The number 64 fits into 140 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 1352.0
If we take 128 away from 140, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 64

Step 6:
64 can be fit into 128 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 13522.0
Subtracting 128 from 128 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 7:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13522.0
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.

Advancing to step 8:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13522.0
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.

The final result is 13522.0 with a remainder of 0.0.
