81458 divided by 64 
The aim is to understand the frequency of 64 in 81458.

Moving on to step 1:
64 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 64

Let's proceed to step 2:
64 goes into 81 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 64 from 81 to get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 64

On to step 3:
64 can be fit into 174 2 times, resulting in a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 128 from 174, we get 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 64

Going ahead to step 4:
When dividing 465 by 64, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Subtract 448 from 465 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 64

Step 5:
178 divided by 64 is 2 with a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 1272.0
Deduct 128 from 178 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 6:
500 divided by 64 is 7 with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 1272.7
If we subtract 448 from 500, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
The number 64 fits into 520 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1272.78
Deduct 512 from 520 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 64 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1272.781
If we subtract 64 from 80, we get 16.
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 9:
64 can be fit into 160 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1272.7812
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 10:
320 divided by 64 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1272.78125
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.

Step 11:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1272.78125
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.

On to 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: 1272.78125
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 1272.78125 with a remaining 0.0.
