We're dividing 81355700 by 256 
We want to figure out the number of times 81355700 can be divided by 256.

Let's proceed to step 1:
8 divided by 256 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 256

Moving on to step 2:
256 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 256

Advancing to step 3:
When dividing 813 by 256, we get 3 with a remainder of 45.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 45 after subtracting 768 from 813.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 256

On to step 4:
256 can be fit into 455 1 times, resulting in a remainder of 199.
The next digit of our result is 1. 
Result so far: 31.0
The remainder is 199 after subtracting 256 from 455.
Fetch the next digit (5) from the dividend, attach it to 199 and continue: 1995 / 256

Step 5:
256 goes into 1995 7 times with a remainder of 203.
The number 7 becomes the next digit in our result. 
Result so far: 317.0
If we take 1792 away from 1995, we end up with 203.
Bring next digit (7) of the dividend behind the 203 and repeat the process: 2037 / 256

Moving on to step 6:
256 goes into 2037 7 times with a remainder of 245.
The number 7 becomes the next digit in our result. 
Result so far: 3177.0
If we take 1792 away from 2037, we end up with 245.
Grab the next digit (0) from the dividend, add it to 245, then carry on: 2450 / 256

Step 7:
2450 divided by 256 is 9 with a remainder of 146.
The next digit of our result is 9. 
Result so far: 31779.0
If we take 2304 away from 2450, we end up with 146.
Include the next digit (0) from the dividend after 146, then repeat: 1460 / 256

Advancing to step 8:
1460 divided by 256 is 5 with a remainder of 180.
The number 5 becomes the next digit in our result. 
Result so far: 317795.0
Subtract 1280 from 1460 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
When dividing 1800 by 256, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 317795.7
If we take 1792 away from 1800, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 256, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 317795.7
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
256 goes into 800 3 times with a remainder of 32.
The next digit of our result is 3. 
Result so far: 317795.703
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 12:
256 can be fit into 320 1 times, resulting in a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 317795.7031
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 13:
640 divided by 256 is 2 with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 317795.70312
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.

Let's proceed to step 14:
256 goes into 1280 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 317795.703125
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.

Going ahead to step 15:
When dividing 0 by 256, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 317795.703125
Subtract 0 from 0 to 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.

Moving on to step 16:
256 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 317795.703125
Subtracting 0 from 0 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.

The final outcome is 317795.703125, with a leftover of 0.0.
