We're dividing 61725016 by 64 
The aim is to understand the frequency of 64 in 61725016.

Step 1:
When dividing 6 by 64, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 64

Moving on to step 2:
64 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 64

Let's proceed to step 3:
If we divide 617 by 64, we get 9 and a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 576 from 617 to get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 64

Let's proceed to step 4:
64 goes into 412 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 384 away from 412, we end up with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 64

Advancing to step 5:
If we divide 285 by 64, we get 4 and a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 964.0
Subtract 256 from 285 to get 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 64

Step 6:
If we divide 290 by 64, we get 4 and a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 9644.0
If we take 256 away from 290, we end up with 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 64

Step 7:
When dividing 341 by 64, we get 5 with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 96445.0
Subtracting 320 from 341 leaves us with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 64

Moving on to step 8:
216 divided by 64 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 964453.0
Deduct 192 from 216 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
64 can be fit into 240 3 times, resulting in a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 964453.3
Deduct 192 from 240 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
When dividing 480 by 64, we get 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 964453.37
If we take 448 away from 480, we end up 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 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 964453.375
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.

Going ahead to step 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 964453.375
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.

Going ahead to step 13:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 964453.375
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 quotient of the division is 964453.375, and the remainder is 0.0.
