252564 ÷ 64 
The aim is to understand the frequency of 64 in 252564.

Let's proceed to step 1:
64 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 64

Moving on to step 2:
When dividing 25 by 64, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 64

Going ahead to step 3:
If we divide 252 by 64, we get 3 and a remainder of 60.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 60 after subtracting 192 from 252.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 64

Let's proceed to step 4:
The number 64 fits into 605 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 576 from 605 to get 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 64

Going ahead to step 5:
If we divide 296 by 64, we get 4 and a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
If we subtract 256 from 296, we get 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 64

Moving on to step 6:
If we divide 404 by 64, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 3946.0
The remainder is 20 after subtracting 384 from 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
64 can be fit into 200 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3946.3
Deduct 192 from 200 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
64 goes into 80 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 3946.31
Subtracting 64 from 80 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 64, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 3946.312
Deduct 128 from 160 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.

Going ahead to step 10:
64 goes into 320 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3946.3125
If we subtract 320 from 320, 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.

Let's proceed to step 11:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3946.3125
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.

Step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3946.3125
Subtract 0 from 0 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.

The final outcome is 3946.3125, with a leftover of 0.0.
