380641 ÷ 64 
The aim is to understand the frequency of 64 in 380641.

On to step 1:
64 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 64

Going ahead to step 2:
If we divide 38 by 64, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 64

Moving on to step 3:
64 goes into 380 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 320 from 380, we get 60.
Take the next digit (6) from the dividend and append it to 60, then repeat: 606 / 64

Let's proceed to step 4:
606 divided by 64 is 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtracting 576 from 606 leaves us with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 64

On to step 5:
The number 64 fits into 304 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 594.0
The remainder is 48 after subtracting 256 from 304.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 64

On to step 6:
When dividing 481 by 64, we get 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 5947.0
The remainder is 33 after subtracting 448 from 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
64 can be fit into 330 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 5947.5
If we take 320 away from 330, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 64 fits into 100 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 5947.51
If we take 64 away from 100, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
360 divided by 64 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 5947.515
Subtract 320 from 360 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
64 can be fit into 400 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 5947.5156
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 5947.51562
If we take 128 away from 160, 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:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5947.515625
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.

Step 13:
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: 5947.515625
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.

Let's proceed to step 14:
0 divided by 64 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5947.515625
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.

The quotient of the division is 5947.515625, and the remainder is 0.0.
