We're dividing 867091 by 77 
We want to divide 867091 by 77.

Step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 77

On to step 2:
77 goes into 86 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 77 from 86 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 77

Let's proceed to step 3:
97 divided by 77 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 77 from 97 to get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 77

Let's proceed to step 4:
The number 77 fits into 200 2 times, leaving a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtracting 154 from 200 leaves us with 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 77

On to step 5:
77 goes into 469 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 1126.0
Subtracting 462 from 469 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 77

On to step 6:
When dividing 71 by 77, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 11260.0
Subtract 0 from 71 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
77 goes into 710 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 11260.9
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
77 can be fit into 170 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 11260.92
Deduct 154 from 170 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 77 fits into 160 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 11260.922
Deduct 154 from 160 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 11260.922 with a remaining 0.0006.
