We're dividing 561548 by 64 
The aim is to understand the frequency of 64 in 561548.

Let's proceed to step 1:
5 divided by 64 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 64

Going ahead to step 2:
If we divide 56 by 64, we get 0 and a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 64

Moving on to step 3:
When dividing 561 by 64, we get 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 512 from 561 leaves us with 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 64

On to step 4:
When dividing 495 by 64, we get 7 with a remainder of 47.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 448 from 495 leaves us with 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 64

Step 5:
474 divided by 64 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 877.0
Subtracting 448 from 474 leaves us with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 64

Let's proceed to step 6:
When dividing 268 by 64, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8774.0
Deduct 256 from 268 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
64 goes into 120 1 times with a remainder of 56.
The next digit of our result is 1. 
Result so far: 8774.1
Deduct 64 from 120 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
The number 64 fits into 560 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8774.18
Subtract 512 from 560 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 8774.187
If we subtract 448 from 480, 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.

Let's proceed to step 10:
If we divide 320 by 64, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 8774.1875
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.

Advancing to step 11:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8774.1875
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.

Step 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8774.1875
Subtracting 0 from 0 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.

The final result is 8774.1875 with a remainder of 0.0.
