80545211 ÷ 857 
We want to figure out the number of times 80545211 can be divided by 857.

Advancing to step 1:
857 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 857

Let's proceed to step 2:
80 divided by 857 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 857

Step 3:
857 can be fit into 805 0 times, resulting in a remainder of 805.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 805 leaves us with 805.
Include the next digit (4) from the dividend after 805, then repeat: 8054 / 857

Moving on to step 4:
When dividing 8054 by 857, we get 9 with a remainder of 341.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7713 away from 8054, we end up with 341.
Include the next digit (5) from the dividend after 341, then repeat: 3415 / 857

Advancing to step 5:
3415 divided by 857 is 3 with a remainder of 844.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 2571 away from 3415, we end up with 844.
Bring next digit (2) of the dividend behind the 844 and repeat the process: 8442 / 857

Going ahead to step 6:
857 can be fit into 8442 9 times, resulting in a remainder of 729.
Record the quotient 9 as the next digit in the result. 
Result so far: 939.0
If we take 7713 away from 8442, we end up with 729.
Bring next digit (1) of the dividend behind the 729 and repeat the process: 7291 / 857

On to step 7:
7291 divided by 857 is 8 with a remainder of 435.
Record the quotient 8 as the next digit in the result. 
Result so far: 9398.0
If we take 6856 away from 7291, we end up with 435.
Bring next digit (1) of the dividend behind the 435 and repeat the process: 4351 / 857

Step 8:
When dividing 4351 by 857, we get 5 with a remainder of 66.
Record the quotient 5 as the next digit in the result. 
Result so far: 93985.0
Subtract 4285 from 4351 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
857 goes into 660 0 times with a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 93985.0
Subtract 0 from 660 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 10:
The number 857 fits into 6600 7 times, leaving a remainder of 601.
Put 7 as the next digit of the answer. 
Result so far: 93985.07
Deduct 5999 from 6600 and we're left with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Going ahead to step 11:
857 goes into 6010 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 93985.077
Subtracting 5999 from 6010 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 93985.077 with a remainder of 0.0011.
