We're dividing 764686 by 64 
The aim is to understand the frequency of 64 in 764686.

Going ahead to step 1:
64 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 64

On to step 2:
64 can be fit into 76 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 64 away from 76, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 64

On to step 3:
The number 64 fits into 124 1 times, leaving a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 60 after subtracting 64 from 124.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 64

Step 4:
606 divided by 64 is 9 with a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 119.0
Deduct 576 from 606 and we're left with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 64

Moving on to step 5:
If we divide 308 by 64, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 1194.0
The remainder is 52 after subtracting 256 from 308.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 64

Moving on to step 6:
When dividing 526 by 64, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 11948.0
If we take 512 away from 526, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 64, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 11948.2
Subtract 128 from 140 to 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.

Going ahead to step 8:
64 can be fit into 120 1 times, resulting in a remainder of 56.
The next digit of our result is 1. 
Result so far: 11948.21
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.

Going ahead to step 9:
If we divide 560 by 64, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 11948.218
The remainder is 48 after subtracting 512 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
When dividing 480 by 64, we get 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 11948.2187
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.

Going ahead to step 11:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11948.21875
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.

On to step 12:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11948.21875
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.

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: 11948.21875
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.

Our division results in 11948.21875 with a remaining 0.0.
