Let's divide 869612 by 77
We want to divide 869612 by 77.

Step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 77

Let's proceed to step 2:
The number 77 fits into 86 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 9 after subtracting 77 from 86.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 77

Step 3:
The number 77 fits into 99 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 77 from 99, we get 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 77

Going ahead to step 4:
If we divide 226 by 77, we get 2 and a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we take 154 away from 226, we end up with 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 77

Moving on to step 5:
721 divided by 77 is 9 with a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 1129.0
Deduct 693 from 721 and we're left with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 77

Step 6:
When dividing 282 by 77, we get 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 11293.0
The remainder is 51 after subtracting 231 from 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
When dividing 510 by 77, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 11293.6
Subtracting 462 from 510 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
If we divide 480 by 77, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 11293.66
If we take 462 away from 480, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 11293.66 with a remainder of 0.018.
