We're dividing 854431 by 64 
The aim is to understand the frequency of 64 in 854431.

Moving on to step 1:
The number 64 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 64

Advancing to step 2:
64 goes into 85 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 64 away from 85, we end up with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 64

Let's proceed to step 3:
64 can be fit into 214 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 192 from 214 leaves us with 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 64

Moving on to step 4:
64 can be fit into 224 3 times, resulting in a remainder of 32.
The next digit of our result is 3. 
Result so far: 133.0
The remainder is 32 after subtracting 192 from 224.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 64

Moving on to step 5:
64 goes into 323 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 1335.0
Deduct 320 from 323 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 64

Going ahead to step 6:
64 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 13350.0
If we take 0 away from 31, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
If we divide 310 by 64, we get 4 and a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 13350.4
If we subtract 256 from 310, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
64 goes into 540 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 13350.48
Deduct 512 from 540 and we're left 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.

Step 9:
When dividing 280 by 64, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 13350.484
Subtracting 256 from 280 leaves us 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.

Going ahead to step 10:
64 goes into 240 3 times with a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 13350.4843
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.

Let's proceed to step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 13350.48437
If we take 448 away from 480, we end up 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:
When dividing 320 by 64, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 13350.484375
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.

Advancing to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13350.484375
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.

Going ahead to step 14:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13350.484375
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 result is 13350.484375 with a remainder of 0.0.
