128543 divided by 64 
The aim is to understand the frequency of 64 in 128543.

On to step 1:
1 divided by 64 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 64

Let's proceed to step 2:
The number 64 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 64

Let's proceed to step 3:
64 goes into 128 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 128 from 128.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 64

Advancing to step 4:
The number 64 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 64

Moving on to step 5:
When dividing 54 by 64, we get 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Subtract 0 from 54 to get 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 64

Going ahead to step 6:
The number 64 fits into 543 8 times, leaving a remainder of 31.
The next digit of our result is 8. 
Result so far: 2008.0
If we subtract 512 from 543, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
310 divided by 64 is 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 2008.4
Deduct 256 from 310 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
64 can be fit into 540 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 2008.48
Subtracting 512 from 540 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 64, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2008.484
Deduct 256 from 280 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.

Step 10:
When dividing 240 by 64, we get 3 with a remainder of 48.
The next digit of our result is 3. 
Result so far: 2008.4843
The remainder is 48 after subtracting 192 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 2008.48437
Deduct 448 from 480 and we're left 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.

Let's proceed to step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 2008.484375
Deduct 320 from 320 and we're left 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.

Going ahead to step 13:
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: 2008.484375
Deduct 0 from 0 and we're left 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.

Advancing to step 14:
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: 2008.484375
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.

In conclusion, the division gives 2008.484375 with a balance of 0.0.
