We look at the division of 64220297 by 512 
The aim is to understand the frequency of 512 in 64220297.

Step 1:
512 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 512

Step 2:
If we divide 64 by 512, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 512

Step 3:
642 divided by 512 is 1 with a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 512 from 642 leaves us with 130.
Take the next digit (2) from the dividend and append it to 130, then repeat: 1302 / 512

Going ahead to step 4:
The number 512 fits into 1302 2 times, leaving a remainder of 278.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1024 away from 1302, we end up with 278.
Grab the next digit (0) from the dividend, add it to 278, then carry on: 2780 / 512

Step 5:
512 goes into 2780 5 times with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Deduct 2560 from 2780 and we're left with 220.
Include the next digit (2) from the dividend after 220, then repeat: 2202 / 512

Advancing to step 6:
When dividing 2202 by 512, we get 4 with a remainder of 154.
Record the quotient 4 as the next digit in the result. 
Result so far: 1254.0
If we take 2048 away from 2202, we end up with 154.
Fetch the next digit (9) from the dividend, attach it to 154 and continue: 1549 / 512

On to step 7:
If we divide 1549 by 512, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 12543.0
Deduct 1536 from 1549 and we're left with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 512

Let's proceed to step 8:
512 goes into 137 0 times with a remainder of 137.
Record the quotient 0 as the next digit in the result. 
Result so far: 125430.0
Subtract 0 from 137 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 9:
1370 divided by 512 is 2 with a remainder of 346.
Use 2 as the next digit of our solution. 
Result so far: 125430.2
If we subtract 1024 from 1370, we get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 10:
If we divide 3460 by 512, we get 6 and a remainder of 388.
Put 6 as the next digit of the answer. 
Result so far: 125430.26
Subtracting 3072 from 3460 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
512 goes into 3880 7 times with a remainder of 296.
The next digit of our result is 7. 
Result so far: 125430.267
Deduct 3584 from 3880 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 12:
The number 512 fits into 2960 5 times, leaving a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 125430.2675
Subtracting 2560 from 2960 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
4000 divided by 512 is 7 with a remainder of 416.
The number 7 becomes the next digit in our result. 
Result so far: 125430.26757
The remainder is 416 after subtracting 3584 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 14:
When dividing 4160 by 512, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 125430.267578
Subtracting 4096 from 4160 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
If we divide 640 by 512, we get 1 and a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 125430.2675781
If we take 512 away from 640, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 16:
If we divide 1280 by 512, we get 2 and a remainder of 256.
Write down 2 as next digit of the result. 
Result so far: 125430.26757812
If we take 1024 away from 1280, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 125430.26757812, with a leftover of 2.56e-07.
