We look at the division of 684004 by 64 
The aim is to understand the frequency of 64 in 684004.

Let's proceed to step 1:
64 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 64

Moving on to step 2:
64 can be fit into 68 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 64 from 68 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 64

Step 3:
When dividing 44 by 64, we get 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 44 to get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 64

Advancing to step 4:
The number 64 fits into 440 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
Subtracting 384 from 440 leaves us with 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 64

On to step 5:
64 goes into 560 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 1068.0
Subtracting 512 from 560 leaves us with 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 64

Moving on to step 6:
The number 64 fits into 484 7 times, leaving a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 10687.0
If we take 448 away from 484, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
The number 64 fits into 360 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 10687.5
Subtracting 320 from 360 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 64, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 10687.56
Subtract 384 from 400 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 10687.562
If we take 128 away from 160, we end up 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.

Step 10:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10687.5625
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.

On to step 11:
If we divide 0 by 64, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10687.5625
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.

Advancing to step 12:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10687.5625
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.

The quotient of the division is 10687.5625, and the remainder is 0.0.
