We're dividing 814420 by 64 
The aim is to understand the frequency of 64 in 814420.

Going ahead to step 1:
The number 64 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 64

Step 2:
If we divide 81 by 64, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 64 from 81 and we're left with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 64

Going ahead to step 3:
64 goes into 174 2 times with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 128 from 174 leaves us with 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 64

Going ahead to step 4:
64 can be fit into 464 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 127.0
If we take 448 away from 464, we end up with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 64

Let's proceed to step 5:
If we divide 162 by 64, we get 2 and a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 1272.0
If we take 128 away from 162, we end up with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 64

Step 6:
If we divide 340 by 64, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 12725.0
The remainder is 20 after subtracting 320 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
200 divided by 64 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 12725.3
Subtracting 192 from 200 leaves us 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.

Moving on to step 8:
80 divided by 64 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 12725.31
The remainder is 16 after subtracting 64 from 80.
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:
When dividing 160 by 64, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 12725.312
Deduct 128 from 160 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.

Advancing to step 10:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12725.3125
If we take 320 away from 320, 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.

Step 11:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12725.3125
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.

Advancing to step 12:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12725.3125
If we subtract 0 from 0, 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.

The final result is 12725.3125 with a remainder of 0.0.
