We're dividing 768635 by 64 
The aim is to understand the frequency of 64 in 768635.

Advancing 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
Subtracting 0 from 7 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 64

Step 2:
76 divided by 64 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 64 from 76 and we're left with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 64

Let's proceed to step 3:
If we divide 128 by 64, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 128 from 128 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 64

Moving on to step 4:
64 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 64

Let's proceed to step 5:
When dividing 63 by 64, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 1200.0
The remainder is 63 after subtracting 0 from 63.
Grab the next digit (5) from the dividend, add it to 63, then carry on: 635 / 64

Advancing to step 6:
635 divided by 64 is 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 12009.0
Subtract 576 from 635 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
The number 64 fits into 590 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 12009.9
Subtracting 576 from 590 leaves us 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.

Advancing to step 8:
64 goes into 140 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 12009.92
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.

Moving on to step 9:
When dividing 120 by 64, we get 1 with a remainder of 56.
Record the quotient 1 as the next digit in the result. 
Result so far: 12009.921
Subtracting 64 from 120 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.

Going ahead to step 10:
64 goes into 560 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 12009.9218
Subtracting 512 from 560 leaves us 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.

Going ahead to step 11:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 12009.92187
The remainder is 32 after subtracting 448 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing 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: 12009.921875
If we take 320 away from 320, 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.

Let's proceed to step 13:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12009.921875
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.

Moving on to step 14:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12009.921875
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.

The quotient of the division is 12009.921875, and the remainder is 0.0.
