We're dividing 209739 by 64 
The aim is to understand the frequency of 64 in 209739.

Step 1:
64 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 64

Advancing to step 2:
64 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 64

Step 3:
When dividing 209 by 64, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 192 from 209 and we're left with 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 64

Moving on to step 4:
64 can be fit into 177 2 times, resulting in a remainder of 49.
The next digit of our result is 2. 
Result so far: 32.0
If we subtract 128 from 177, we get 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 64

Advancing to step 5:
64 can be fit into 493 7 times, resulting in a remainder of 45.
The next digit of our result is 7. 
Result so far: 327.0
Deduct 448 from 493 and we're left with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 64

Advancing to step 6:
If we divide 459 by 64, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 3277.0
The remainder is 11 after subtracting 448 from 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
64 goes into 110 1 times with a remainder of 46.
The next digit of our result is 1. 
Result so far: 3277.1
Subtracting 64 from 110 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
The number 64 fits into 460 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 3277.17
If we subtract 448 from 460, we 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.

On to step 9:
64 goes into 120 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 3277.171
Subtract 64 from 120 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
64 goes into 560 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 3277.1718
Deduct 512 from 560 and we're left 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 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: 3277.17187
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.

On to step 12:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3277.171875
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.

Let's proceed to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3277.171875
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.

Advancing to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3277.171875
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 final result is 3277.171875 with a remainder of 0.0.
