We're dividing 20125 by 64 
The aim is to understand the frequency of 64 in 20125.

Let's proceed to step 1:
64 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 64

Going ahead to step 2:
If we divide 20 by 64, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 64

Moving on to step 3:
64 can be fit into 201 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 9 after subtracting 192 from 201.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 64

Step 4:
64 goes into 92 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 64 from 92, we get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 64

Let's proceed to step 5:
The number 64 fits into 285 4 times, leaving a remainder of 29.
The next digit of our result is 4. 
Result so far: 314.0
The remainder is 29 after subtracting 256 from 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 6:
290 divided by 64 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 314.4
If we subtract 256 from 290, we 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.

On to step 7:
When dividing 340 by 64, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 314.45
The remainder is 20 after subtracting 320 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
64 goes into 200 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 314.453
The remainder is 8 after subtracting 192 from 200.
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 9:
64 goes into 80 1 times with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 314.4531
If we take 64 away from 80, we end up 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.

Moving on to step 10:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 314.45312
Subtracting 128 from 160 leaves us 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.

On to step 11:
When dividing 320 by 64, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 314.453125
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
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: 314.453125
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 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 314.453125
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 outcome is 314.453125, with a leftover of 0.0.
