We're dividing 257890 by 64 
The aim is to understand the frequency of 64 in 257890.

Moving on to step 1:
The number 64 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 64

Moving on to step 2:
When dividing 25 by 64, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 64

Moving on to step 3:
When dividing 257 by 64, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 256 from 257, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 64

On to step 4:
When dividing 18 by 64, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 64

On to step 5:
The number 64 fits into 189 2 times, leaving a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 402.0
Subtracting 128 from 189 leaves us with 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 64

Going ahead to step 6:
The number 64 fits into 610 9 times, leaving a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 4029.0
Subtract 576 from 610 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
64 goes into 340 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 4029.5
If we subtract 320 from 340, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
64 goes into 200 3 times with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 4029.53
Subtract 192 from 200 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
64 can be fit into 80 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 4029.531
The remainder is 16 after subtracting 64 from 80.
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 10:
160 divided by 64 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 4029.5312
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.

On to step 11:
320 divided by 64 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4029.53125
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 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4029.53125
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.

On to step 13:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4029.53125
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.

Our division results in 4029.53125 with a remaining 0.0.
