We're dividing 81228159 by 877 
We're looking to find how many times 877 goes into 81228159.

Moving on to step 1:
877 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 877

Advancing to step 2:
When dividing 81 by 877, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 877

Moving on to step 3:
The number 877 fits into 812 0 times, leaving a remainder of 812.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 812 to get 812.
Grab the next digit (2) from the dividend, add it to 812, then carry on: 8122 / 877

Going ahead to step 4:
When dividing 8122 by 877, we get 9 with a remainder of 229.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7893 from 8122 leaves us with 229.
Bring next digit (8) of the dividend behind the 229 and repeat the process: 2298 / 877

Let's proceed to step 5:
877 can be fit into 2298 2 times, resulting in a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Deduct 1754 from 2298 and we're left with 544.
Grab the next digit (1) from the dividend, add it to 544, then carry on: 5441 / 877

Advancing to step 6:
If we divide 5441 by 877, we get 6 and a remainder of 179.
Record the quotient 6 as the next digit in the result. 
Result so far: 926.0
If we take 5262 away from 5441, we end up with 179.
Grab the next digit (5) from the dividend, add it to 179, then carry on: 1795 / 877

Advancing to step 7:
1795 divided by 877 is 2 with a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 9262.0
If we take 1754 away from 1795, we end up with 41.
Bring next digit (9) of the dividend behind the 41 and repeat the process: 419 / 877

Let's proceed to step 8:
877 can be fit into 419 0 times, resulting in a remainder of 419.
The next digit of our result is 0. 
Result so far: 92620.0
The remainder is 419 after subtracting 0 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 9:
877 can be fit into 4190 4 times, resulting in a remainder of 682.
The number 4 becomes the next digit in our result. 
Result so far: 92620.4
The remainder is 682 after subtracting 3508 from 4190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Advancing to step 10:
If we divide 6820 by 877, we get 7 and a remainder of 681.
Use 7 as the next digit of our solution. 
Result so far: 92620.47
If we subtract 6139 from 6820, we get 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

On to step 11:
When dividing 6810 by 877, we get 7 with a remainder of 671.
Record the quotient 7 as the next digit in the result. 
Result so far: 92620.477
Subtract 6139 from 6810 to get 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

The final result is 92620.477 with a remainder of 0.0671.
