68777171 ÷ 891 
Our goal is to divide 68777171 by 891.

On to step 1:
The number 891 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 891

On to step 2:
When dividing 68 by 891, we get 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 891

Advancing to step 3:
891 goes into 687 0 times with a remainder of 687.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 687, we end up with 687.
Include the next digit (7) from the dividend after 687, then repeat: 6877 / 891

Going ahead to step 4:
When dividing 6877 by 891, we get 7 with a remainder of 640.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6237 from 6877 leaves us with 640.
Take the next digit (7) from the dividend and append it to 640, then repeat: 6407 / 891

Advancing to step 5:
891 can be fit into 6407 7 times, resulting in a remainder of 170.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 6237 from 6407 leaves us with 170.
Include the next digit (1) from the dividend after 170, then repeat: 1701 / 891

Let's proceed to step 6:
891 goes into 1701 1 times with a remainder of 810.
Put 1 as the next digit of the answer. 
Result so far: 771.0
Subtracting 891 from 1701 leaves us with 810.
Grab the next digit (7) from the dividend, add it to 810, then carry on: 8107 / 891

On to step 7:
891 can be fit into 8107 9 times, resulting in a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 7719.0
Deduct 8019 from 8107 and we're left with 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 891

On to step 8:
891 can be fit into 881 0 times, resulting in a remainder of 881.
Write down 0 as next digit of the result. 
Result so far: 77190.0
If we take 0 away from 881, we end up with 881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8810, and continue the process.

Advancing to step 9:
When dividing 8810 by 891, we get 9 with a remainder of 791.
Record the quotient 9 as the next digit in the result. 
Result so far: 77190.9
Subtract 8019 from 8810 to get 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Step 10:
When dividing 7910 by 891, we get 8 with a remainder of 782.
Write down 8 as next digit of the result. 
Result so far: 77190.98
Deduct 7128 from 7910 and we're left with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Let's proceed to step 11:
If we divide 7820 by 891, we get 8 and a remainder of 692.
Record the quotient 8 as the next digit in the result. 
Result so far: 77190.988
The remainder is 692 after subtracting 7128 from 7820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

The final outcome is 77190.988, with a leftover of 0.0692.
