809766 divided by 64 
The aim is to understand the frequency of 64 in 809766.

Going ahead to step 1:
8 divided by 64 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 64

Step 2:
80 divided by 64 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 64 from 80, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 64

Advancing to step 3:
64 goes into 169 2 times with a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 128 from 169 leaves us with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 64

Advancing to step 4:
64 can be fit into 417 6 times, resulting in a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
If we take 384 away from 417, we end up with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 64

Moving on to step 5:
When dividing 336 by 64, we get 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 1265.0
If we take 320 away from 336, we end up with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 64

Step 6:
If we divide 166 by 64, we get 2 and a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 12652.0
If we subtract 128 from 166, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
When dividing 380 by 64, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 12652.5
Subtract 320 from 380 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
64 goes into 600 9 times with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 12652.59
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
If we divide 240 by 64, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 12652.593
If we take 192 away from 240, we end up 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.

Advancing to step 10:
64 can be fit into 480 7 times, resulting in a remainder of 32.
The next digit of our result is 7. 
Result so far: 12652.5937
The remainder is 32 after subtracting 448 from 480.
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.
The number 5 becomes the next digit in our result. 
Result so far: 12652.59375
Subtract 320 from 320 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.

Going ahead to step 12:
0 divided by 64 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12652.59375
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.

Moving on to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12652.59375
If we take 0 away from 0, we end up 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 outcome is 12652.59375, with a leftover of 0.0.
