We're dividing 587051 by 64 
The aim is to understand the frequency of 64 in 587051.

On to step 1:
The number 64 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 64

Step 2:
The number 64 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 64

Going ahead to step 3:
64 can be fit into 587 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 576 away from 587, we end up with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 64

Step 4:
The number 64 fits into 110 1 times, leaving a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we take 64 away from 110, we end up with 46.
Take the next digit (5) from the dividend and append it to 46, then repeat: 465 / 64

On to step 5:
465 divided by 64 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 917.0
If we subtract 448 from 465, we get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 64

On to step 6:
171 divided by 64 is 2 with a remainder of 43.
The next digit of our result is 2. 
Result so far: 9172.0
Deduct 128 from 171 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
When dividing 430 by 64, we get 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 9172.6
Subtract 384 from 430 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
64 can be fit into 460 7 times, resulting in a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 9172.67
If we subtract 448 from 460, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 64 is 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 9172.671
Deduct 64 from 120 and we're left 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.

Step 10:
64 can be fit into 560 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 9172.6718
If we subtract 512 from 560, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
64 goes into 480 7 times with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 9172.67187
Subtracting 448 from 480 leaves us 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.

Moving on to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9172.671875
If we subtract 320 from 320, 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.

Moving on to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9172.671875
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.

Moving on to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9172.671875
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.

After the division, we end up with 9172.671875 and a remainder of 0.0.
