83943381 divided by 256 
The aim is to understand the frequency of 256 in 83943381.

Moving on to step 1:
8 divided by 256 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 256

Let's proceed to step 2:
The number 256 fits into 83 0 times, leaving a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 256

Advancing to step 3:
The number 256 fits into 839 3 times, leaving a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 768 from 839, we get 71.
Take the next digit (4) from the dividend and append it to 71, then repeat: 714 / 256

Going ahead to step 4:
If we divide 714 by 256, we get 2 and a remainder of 202.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 512 away from 714, we end up with 202.
Bring next digit (3) of the dividend behind the 202 and repeat the process: 2023 / 256

On to step 5:
256 goes into 2023 7 times with a remainder of 231.
Record the quotient 7 as the next digit in the result. 
Result so far: 327.0
The remainder is 231 after subtracting 1792 from 2023.
Grab the next digit (3) from the dividend, add it to 231, then carry on: 2313 / 256

On to step 6:
2313 divided by 256 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 3279.0
Subtracting 2304 from 2313 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 256

Moving on to step 7:
256 goes into 98 0 times with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 32790.0
Deduct 0 from 98 and we're left with 98.
Grab the next digit (1) from the dividend, add it to 98, then carry on: 981 / 256

Advancing to step 8:
When dividing 981 by 256, we get 3 with a remainder of 213.
Write down 3 as next digit of the result. 
Result so far: 327903.0
The remainder is 213 after subtracting 768 from 981.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 9:
256 goes into 2130 8 times with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 327903.8
Subtract 2048 from 2130 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
When dividing 820 by 256, we get 3 with a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 327903.83
Subtract 768 from 820 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
If we divide 520 by 256, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 327903.832
Subtract 512 from 520 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
256 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 327903.832
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
800 divided by 256 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 327903.83203
Deduct 768 from 800 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
When dividing 320 by 256, we get 1 with a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 327903.832031
Subtract 256 from 320 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 15:
640 divided by 256 is 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 327903.8320312
Deduct 512 from 640 and we're left 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.

Let's proceed to step 16:
1280 divided by 256 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 327903.83203125
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.

After the division, we end up with 327903.83203125 and a remainder of 0.0.
