We look at the division of 25970570 by 256 
The aim is to understand the frequency of 256 in 25970570.

Going ahead to step 1:
If we divide 2 by 256, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 256

Step 2:
If we divide 25 by 256, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 256

Advancing to step 3:
256 can be fit into 259 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 256 from 259, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 256

Going ahead to step 4:
The number 256 fits into 37 0 times, leaving a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 37, we end up with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 256

Moving on to step 5:
256 can be fit into 370 1 times, resulting in a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 256 away from 370, we end up with 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 256

On to step 6:
When dividing 1145 by 256, we get 4 with a remainder of 121.
Write down 4 as next digit of the result. 
Result so far: 1014.0
If we subtract 1024 from 1145, we get 121.
Take the next digit (7) from the dividend and append it to 121, then repeat: 1217 / 256

Going ahead to step 7:
If we divide 1217 by 256, we get 4 and a remainder of 193.
Write down 4 as next digit of the result. 
Result so far: 10144.0
If we take 1024 away from 1217, we end up with 193.
Take the next digit (0) from the dividend and append it to 193, then repeat: 1930 / 256

Going ahead to step 8:
1930 divided by 256 is 7 with a remainder of 138.
Use 7 as the next digit of our solution. 
Result so far: 101447.0
Subtracting 1792 from 1930 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 9:
If we divide 1380 by 256, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 101447.5
Subtract 1280 from 1380 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
256 can be fit into 1000 3 times, resulting in a remainder of 232.
Record the quotient 3 as the next digit in the result. 
Result so far: 101447.53
If we subtract 768 from 1000, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 11:
The number 256 fits into 2320 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 101447.539
Subtract 2304 from 2320 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
If we divide 160 by 256, we get 0 and a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 101447.539
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
256 goes into 1600 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 101447.53906
Deduct 1536 from 1600 and we're left 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.

On to step 14:
If we divide 640 by 256, we get 2 and a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 101447.539062
Subtracting 512 from 640 leaves us 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 15:
256 goes into 1280 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 101447.5390625
Subtracting 1280 from 1280 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 16:
256 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 101447.5390625
If we subtract 0 from 0, 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 outcome is 101447.5390625, with a leftover of 0.0.
