We're dividing 771171 by 64 
The aim is to understand the frequency of 64 in 771171.

Moving on to step 1:
The number 64 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 64

Advancing to step 2:
The number 64 fits into 77 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 13 after subtracting 64 from 77.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 64

Step 3:
131 divided by 64 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 128 from 131, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 64

Step 4:
If we divide 31 by 64, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtract 0 from 31 to get 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 64

Let's proceed to step 5:
If we divide 317 by 64, we get 4 and a remainder of 61.
The next digit of our result is 4. 
Result so far: 1204.0
Subtracting 256 from 317 leaves us with 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 64

Let's proceed to step 6:
611 divided by 64 is 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 12049.0
Deduct 576 from 611 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
When dividing 350 by 64, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 12049.5
The remainder is 30 after subtracting 320 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 64, we get 4 and a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 12049.54
If we take 256 away from 300, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
If we divide 440 by 64, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 12049.546
Subtracting 384 from 440 leaves us 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.

On to step 10:
When dividing 560 by 64, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 12049.5468
If we take 512 away from 560, 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.

Moving on to 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: 12049.54687
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.

Moving on to step 12:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12049.546875
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.

Step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12049.546875
Subtracting 0 from 0 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 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12049.546875
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 12049.546875 with a remainder of 0.0.
