We look at the division of 12506625 by 64 
The aim is to understand the frequency of 64 in 12506625.

Going ahead to step 1:
1 divided by 64 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 64

Going ahead to step 2:
64 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 64

Moving on to step 3:
The number 64 fits into 125 1 times, leaving a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 64 away from 125, we end up with 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 64

On to step 4:
64 goes into 610 9 times with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 576 away from 610, we end up with 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 64

Let's proceed to step 5:
64 can be fit into 346 5 times, resulting in a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Deduct 320 from 346 and we're left with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 64

Going ahead to step 6:
When dividing 266 by 64, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1954.0
Subtract 256 from 266 to get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 64

On to step 7:
When dividing 102 by 64, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 19541.0
Subtract 64 from 102 to get 38.
Grab the next digit (5) from the dividend, add it to 38, then carry on: 385 / 64

Going ahead to step 8:
The number 64 fits into 385 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 195416.0
If we subtract 384 from 385, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
64 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 195416.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 64 fits into 100 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 195416.01
If we take 64 away from 100, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
64 can be fit into 360 5 times, resulting in a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 195416.015
Subtract 320 from 360 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
64 can be fit into 400 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 195416.0156
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
When dividing 160 by 64, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 195416.01562
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
320 divided by 64 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 195416.015625
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 15:
If we divide 0 by 64, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 195416.015625
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.

Moving on to step 16:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 195416.015625
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.

Our division results in 195416.015625 with a remaining 0.0.
