Let's divide 21955091 by 64
The aim is to understand the frequency of 64 in 21955091.

Step 1:
The number 64 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 64

On to step 2:
If we divide 21 by 64, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 64

Step 3:
219 divided by 64 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 192 from 219 to get 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 64

Moving on to step 4:
If we divide 275 by 64, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 256 from 275, we get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 64

Going ahead to step 5:
The number 64 fits into 195 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 343.0
Subtracting 192 from 195 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 64

On to step 6:
The number 64 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3430.0
If we take 0 away from 30, we end up with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 64

Let's proceed to step 7:
309 divided by 64 is 4 with a remainder of 53.
The next digit of our result is 4. 
Result so far: 34304.0
The remainder is 53 after subtracting 256 from 309.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 64

On to step 8:
When dividing 531 by 64, we get 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 343048.0
Subtracting 512 from 531 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
64 can be fit into 190 2 times, resulting in a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 343048.2
If we take 128 away from 190, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
64 can be fit into 620 9 times, resulting in a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 343048.29
If we subtract 576 from 620, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
64 goes into 440 6 times with a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 343048.296
If we take 384 away from 440, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
64 goes into 560 8 times with a remainder of 48.
The next digit of our result is 8. 
Result so far: 343048.2968
Subtracting 512 from 560 leaves us 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.

Moving on to step 13:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 343048.29687
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.

On to step 14:
64 goes into 320 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 343048.296875
Deduct 320 from 320 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.

On to step 15:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 343048.296875
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.

On to step 16:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 343048.296875
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 final result is 343048.296875 with a remainder of 0.0.
