We look at the division of 72671405 by 512 
The aim is to understand the frequency of 512 in 72671405.

Step 1:
512 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 512

Let's proceed to step 2:
512 can be fit into 72 0 times, resulting in a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (6) from the dividend to 72 and continue with: 726 / 512

Going ahead to step 3:
512 can be fit into 726 1 times, resulting in a remainder of 214.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 512 from 726 and we're left with 214.
Include the next digit (7) from the dividend after 214, then repeat: 2147 / 512

Going ahead to step 4:
The number 512 fits into 2147 4 times, leaving a remainder of 99.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 2048 away from 2147, we end up with 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 512

Step 5:
The number 512 fits into 991 1 times, leaving a remainder of 479.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Deduct 512 from 991 and we're left with 479.
Include the next digit (4) from the dividend after 479, then repeat: 4794 / 512

On to step 6:
The number 512 fits into 4794 9 times, leaving a remainder of 186.
Record the quotient 9 as the next digit in the result. 
Result so far: 1419.0
Deduct 4608 from 4794 and we're left with 186.
Bring next digit (0) of the dividend behind the 186 and repeat the process: 1860 / 512

Going ahead to step 7:
If we divide 1860 by 512, we get 3 and a remainder of 324.
Record the quotient 3 as the next digit in the result. 
Result so far: 14193.0
The remainder is 324 after subtracting 1536 from 1860.
Fetch the next digit (5) from the dividend, attach it to 324 and continue: 3245 / 512

Going ahead to step 8:
3245 divided by 512 is 6 with a remainder of 173.
Write down 6 as next digit of the result. 
Result so far: 141936.0
Subtract 3072 from 3245 to get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 9:
The number 512 fits into 1730 3 times, leaving a remainder of 194.
Put 3 as the next digit of the answer. 
Result so far: 141936.3
Subtract 1536 from 1730 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 10:
512 can be fit into 1940 3 times, resulting in a remainder of 404.
Record the quotient 3 as the next digit in the result. 
Result so far: 141936.33
If we take 1536 away from 1940, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Our division results in 141936.33 with a remaining 0.404.
