We divide 7900007 by 512
The aim is to understand the frequency of 512 in 7900007.

Going ahead to step 1:
If we divide 7 by 512, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 512

Moving on to step 2:
512 goes into 79 0 times with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 512

Step 3:
When dividing 790 by 512, we get 1 with a remainder of 278.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 512 from 790 leaves us with 278.
Grab the next digit (0) from the dividend, add it to 278, then carry on: 2780 / 512

Going ahead to step 4:
512 can be fit into 2780 5 times, resulting in a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2560 from 2780, we get 220.
Grab the next digit (0) from the dividend, add it to 220, then carry on: 2200 / 512

Let's proceed to step 5:
2200 divided by 512 is 4 with a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we take 2048 away from 2200, we end up with 152.
Include the next digit (0) from the dividend after 152, then repeat: 1520 / 512

Going ahead to step 6:
If we divide 1520 by 512, we get 2 and a remainder of 496.
The next digit of our result is 2. 
Result so far: 1542.0
Deduct 1024 from 1520 and we're left with 496.
Include the next digit (7) from the dividend after 496, then repeat: 4967 / 512

Step 7:
512 goes into 4967 9 times with a remainder of 359.
Write down 9 as next digit of the result. 
Result so far: 15429.0
Subtract 4608 from 4967 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 8:
If we divide 3590 by 512, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 15429.7
Deduct 3584 from 3590 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
512 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 15429.7
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 512 fits into 600 1 times, leaving a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 15429.701
Subtract 512 from 600 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
512 can be fit into 880 1 times, resulting in a remainder of 368.
Put 1 as the next digit of the answer. 
Result so far: 15429.7011
Subtracting 512 from 880 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 15429.7011 and a remainder of 0.00368.
