We're dividing 943021 by 64 
The aim is to understand the frequency of 64 in 943021.

On to step 1:
If we divide 9 by 64, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 64

Moving on to step 2:
If we divide 94 by 64, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 30 after subtracting 64 from 94.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 64

Going ahead to step 3:
The number 64 fits into 303 4 times, leaving a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 256 away from 303, we end up with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 64

Moving on to step 4:
The number 64 fits into 470 7 times, leaving a remainder of 22.
The next digit of our result is 7. 
Result so far: 147.0
The remainder is 22 after subtracting 448 from 470.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 64

On to step 5:
64 goes into 222 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 1473.0
Deduct 192 from 222 and we're left with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 64

On to step 6:
If we divide 301 by 64, we get 4 and a remainder of 45.
The next digit of our result is 4. 
Result so far: 14734.0
Subtract 256 from 301 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
If we divide 450 by 64, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 14734.7
If we subtract 448 from 450, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 64 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 14734.7
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
64 goes into 200 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 14734.703
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.

Let's proceed to step 10:
80 divided by 64 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 14734.7031
Deduct 64 from 80 and we're left with 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 11:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 14734.70312
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.

Let's proceed to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 14734.703125
Subtracting 320 from 320 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 13:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14734.703125
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.

Moving on to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14734.703125
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 14734.703125 with a remainder of 0.0.
