We're dividing 69939 by 64 
The aim is to understand the frequency of 64 in 69939.

On to step 1:
6 divided by 64 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 64

Moving on to step 2:
64 goes into 69 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 64 from 69 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 64

Going ahead to step 3:
64 can be fit into 59 0 times, resulting in a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 59 after subtracting 0 from 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 64

Let's proceed to step 4:
64 can be fit into 593 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 109.0
Subtract 576 from 593 to get 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 64

Advancing to step 5:
When dividing 179 by 64, we get 2 with a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 1092.0
Subtract 128 from 179 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 6:
510 divided by 64 is 7 with a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 1092.7
The remainder is 62 after subtracting 448 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
If we divide 620 by 64, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 1092.79
Deduct 576 from 620 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
64 can be fit into 440 6 times, resulting in a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 1092.796
The remainder is 56 after subtracting 384 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
64 goes into 560 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 1092.7968
Subtract 512 from 560 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
The number 64 fits into 480 7 times, leaving a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 1092.79687
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.

Step 11:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1092.796875
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.

Let's proceed to step 12:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1092.796875
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.

Step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1092.796875
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 1092.796875, with a leftover of 0.0.
