32815699 divided by 64 
The aim is to understand the frequency of 64 in 32815699.

On to step 1:
If we divide 3 by 64, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 64

On to step 2:
If we divide 32 by 64, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 64

Step 3:
64 goes into 328 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 320 from 328 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 64

Step 4:
When dividing 81 by 64, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 64 from 81 leaves us with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 64

On to step 5:
175 divided by 64 is 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 512.0
Subtracting 128 from 175 leaves us with 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 64

Step 6:
64 can be fit into 476 7 times, resulting in a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 5127.0
If we subtract 448 from 476, we get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 64

On to step 7:
64 can be fit into 289 4 times, resulting in a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 51274.0
If we take 256 away from 289, we end up with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 64

Advancing to step 8:
64 can be fit into 339 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 512745.0
Deduct 320 from 339 and we're left 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.

Going ahead to step 9:
If we divide 190 by 64, we get 2 and a remainder of 62.
The next digit of our result is 2. 
Result so far: 512745.2
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.

On to step 10:
When dividing 620 by 64, we get 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 512745.29
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.

Moving on to step 11:
440 divided by 64 is 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 512745.296
Subtract 384 from 440 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
64 can be fit into 560 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 512745.2968
Deduct 512 from 560 and we're left 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.

Let's proceed to step 13:
480 divided by 64 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 512745.29687
Subtract 448 from 480 to get 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 14:
When dividing 320 by 64, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 512745.296875
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
64 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 512745.296875
Subtract 0 from 0 to 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.

Step 16:
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: 512745.296875
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.

After the division, we end up with 512745.296875 and a remainder of 0.0.
