Let's divide 70368729 by 256
The aim is to understand the frequency of 256 in 70368729.

Advancing to step 1:
If we divide 7 by 256, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 256

Advancing to step 2:
256 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 256

Step 3:
256 can be fit into 703 2 times, resulting in a remainder of 191.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 512 from 703 to get 191.
Fetch the next digit (6) from the dividend, attach it to 191 and continue: 1916 / 256

Going ahead to step 4:
The number 256 fits into 1916 7 times, leaving a remainder of 124.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 1792 away from 1916, we end up with 124.
Grab the next digit (8) from the dividend, add it to 124, then carry on: 1248 / 256

On to step 5:
If we divide 1248 by 256, we get 4 and a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 274.0
The remainder is 224 after subtracting 1024 from 1248.
Bring next digit (7) of the dividend behind the 224 and repeat the process: 2247 / 256

Going ahead to step 6:
If we divide 2247 by 256, we get 8 and a remainder of 199.
Write down 8 as next digit of the result. 
Result so far: 2748.0
If we subtract 2048 from 2247, we get 199.
Append the next digit (2) from the dividend to 199 and continue with: 1992 / 256

Advancing to step 7:
The number 256 fits into 1992 7 times, leaving a remainder of 200.
Use 7 as the next digit of our solution. 
Result so far: 27487.0
If we take 1792 away from 1992, we end up with 200.
Bring next digit (9) of the dividend behind the 200 and repeat the process: 2009 / 256

Let's proceed to step 8:
When dividing 2009 by 256, we get 7 with a remainder of 217.
Put 7 as the next digit of the answer. 
Result so far: 274877.0
If we subtract 1792 from 2009, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 9:
256 can be fit into 2170 8 times, resulting in a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 274877.8
If we take 2048 away from 2170, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 10:
256 can be fit into 1220 4 times, resulting in a remainder of 196.
Put 4 as the next digit of the answer. 
Result so far: 274877.84
Subtract 1024 from 1220 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 11:
The number 256 fits into 1960 7 times, leaving a remainder of 168.
The number 7 becomes the next digit in our result. 
Result so far: 274877.847
If we subtract 1792 from 1960, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
1680 divided by 256 is 6 with a remainder of 144.
The next digit of our result is 6. 
Result so far: 274877.8476
Deduct 1536 from 1680 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 13:
When dividing 1440 by 256, we get 5 with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 274877.84765
If we take 1280 away from 1440, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
1600 divided by 256 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 274877.847656
The remainder is 64 after subtracting 1536 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
640 divided by 256 is 2 with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 274877.8476562
If we subtract 512 from 640, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 16:
256 goes into 1280 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 274877.84765625
If we subtract 1280 from 1280, we 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 result is 274877.84765625 with a remainder of 0.0.
