We're dividing 2109 by 64 
The aim is to understand the frequency of 64 in 2109.

On to step 1:
64 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 64

Advancing to step 2:
21 divided by 64 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 64

Moving on to step 3:
When dividing 210 by 64, we get 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 192 from 210 and we're left with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 64

Let's proceed to step 4:
The number 64 fits into 189 2 times, leaving a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Subtracting 128 from 189 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 5:
64 goes into 610 9 times with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 32.9
Subtract 576 from 610 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 6:
64 goes into 340 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 32.95
If we subtract 320 from 340, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
64 can be fit into 200 3 times, resulting in a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 32.953
Deduct 192 from 200 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 64 fits into 80 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 32.9531
Subtract 64 from 80 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.

Moving on to step 9:
If we divide 160 by 64, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 32.95312
If we subtract 128 from 160, we 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.

Moving on to step 10:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 32.953125
Subtract 320 from 320 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 11:
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: 32.953125
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.

Moving on to step 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32.953125
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 final outcome is 32.953125, with a leftover of 0.0.
