Let's divide 81888865 by 256
The aim is to understand the frequency of 256 in 81888865.

Going ahead to step 1:
256 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 256

On to step 2:
256 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 256

Advancing to step 3:
818 divided by 256 is 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 768 from 818 and we're left with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 256

Step 4:
When dividing 508 by 256, we get 1 with a remainder of 252.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 256 from 508 and we're left with 252.
Append the next digit (8) from the dividend to 252 and continue with: 2528 / 256

On to step 5:
When dividing 2528 by 256, we get 9 with a remainder of 224.
Use 9 as the next digit of our solution. 
Result so far: 319.0
If we take 2304 away from 2528, we end up with 224.
Bring next digit (8) of the dividend behind the 224 and repeat the process: 2248 / 256

Let's proceed to step 6:
2248 divided by 256 is 8 with a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 3198.0
If we subtract 2048 from 2248, we get 200.
Bring next digit (6) of the dividend behind the 200 and repeat the process: 2006 / 256

Let's proceed to step 7:
If we divide 2006 by 256, we get 7 and a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 31987.0
The remainder is 214 after subtracting 1792 from 2006.
Grab the next digit (5) from the dividend, add it to 214, then carry on: 2145 / 256

Step 8:
When dividing 2145 by 256, we get 8 with a remainder of 97.
The next digit of our result is 8. 
Result so far: 319878.0
The remainder is 97 after subtracting 2048 from 2145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
The number 256 fits into 970 3 times, leaving a remainder of 202.
Use 3 as the next digit of our solution. 
Result so far: 319878.3
Subtracting 768 from 970 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
When dividing 2020 by 256, we get 7 with a remainder of 228.
The number 7 becomes the next digit in our result. 
Result so far: 319878.37
The remainder is 228 after subtracting 1792 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
256 can be fit into 2280 8 times, resulting in a remainder of 232.
The next digit of our result is 8. 
Result so far: 319878.378
Subtracting 2048 from 2280 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
256 goes into 2320 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 319878.3789
Subtracting 2304 from 2320 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
The number 256 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 319878.3789
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
The number 256 fits into 1600 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 319878.378906
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.

On to step 15:
When dividing 640 by 256, we get 2 with a remainder of 128.
Write down 2 as next digit of the result. 
Result so far: 319878.3789062
Subtract 512 from 640 to 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.

On to step 16:
The number 256 fits into 1280 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 319878.37890625
The remainder is 0 after subtracting 1280 from 1280.
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 319878.37890625, with a leftover of 0.0.
