We look at the division of 457492 by 64 
The aim is to understand the frequency of 64 in 457492.

Step 1:
4 divided by 64 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 64

On to step 2:
The number 64 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 64

Going ahead to step 3:
64 goes into 457 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 448 from 457, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 64

On to step 4:
64 can be fit into 94 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtracting 64 from 94 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 64

Step 5:
309 divided by 64 is 4 with a remainder of 53.
The next digit of our result is 4. 
Result so far: 714.0
Subtract 256 from 309 to get 53.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 64

Step 6:
64 can be fit into 532 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 7148.0
Subtracting 512 from 532 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
64 goes into 200 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 7148.3
If we take 192 away from 200, we end up 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.

Step 8:
64 can be fit into 80 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 7148.31
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.

Let's proceed to step 9:
64 goes into 160 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 7148.312
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
When dividing 320 by 64, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7148.3125
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.

Step 11:
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: 7148.3125
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.

On to step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7148.3125
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.

The final result is 7148.3125 with a remainder of 0.0.
