We divide 71968994 by 512
The aim is to understand the frequency of 512 in 71968994.

Step 1:
512 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 512

Step 2:
When dividing 71 by 512, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 512

On to step 3:
The number 512 fits into 719 1 times, leaving a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 512 from 719 to get 207.
Grab the next digit (6) from the dividend, add it to 207, then carry on: 2076 / 512

Let's proceed to step 4:
512 goes into 2076 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 2048 away from 2076, we end up with 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 512

Moving on to step 5:
If we divide 288 by 512, we get 0 and a remainder of 288.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtract 0 from 288 to get 288.
Bring next digit (9) of the dividend behind the 288 and repeat the process: 2889 / 512

Moving on to step 6:
If we divide 2889 by 512, we get 5 and a remainder of 329.
Put 5 as the next digit of the answer. 
Result so far: 1405.0
If we take 2560 away from 2889, we end up with 329.
Include the next digit (9) from the dividend after 329, then repeat: 3299 / 512

Moving on to step 7:
512 goes into 3299 6 times with a remainder of 227.
The next digit of our result is 6. 
Result so far: 14056.0
If we take 3072 away from 3299, we end up with 227.
Grab the next digit (4) from the dividend, add it to 227, then carry on: 2274 / 512

Advancing to step 8:
The number 512 fits into 2274 4 times, leaving a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 140564.0
Subtract 2048 from 2274 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 9:
2260 divided by 512 is 4 with a remainder of 212.
The number 4 becomes the next digit in our result. 
Result so far: 140564.4
Subtract 2048 from 2260 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
512 goes into 2120 4 times with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 140564.44
Deduct 2048 from 2120 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 140564.44 with a remainder of 0.072.
