We're dividing 871000 by 64 
The aim is to understand the frequency of 64 in 871000.

Let's proceed to step 1:
When dividing 8 by 64, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 64

Let's proceed to step 2:
If we divide 87 by 64, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 64 from 87 to get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 64

Advancing to step 3:
231 divided by 64 is 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 192 from 231, we get 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 64

Moving on to step 4:
When dividing 390 by 64, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtracting 384 from 390 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 64

Step 5:
64 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1360.0
If we subtract 0 from 60, we get 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 64

Let's proceed to step 6:
600 divided by 64 is 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 13609.0
If we subtract 576 from 600, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
64 can be fit into 240 3 times, resulting in a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 13609.3
If we take 192 away from 240, we end up 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 8:
If we divide 480 by 64, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 13609.37
Deduct 448 from 480 and we're left 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 9:
320 divided by 64 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 13609.375
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 10:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13609.375
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.

Going ahead to step 11:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13609.375
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 13609.375 with a remainder of 0.0.
