Let's divide 866738 by 77
Our goal is to divide 866738 by 77.

Going ahead to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 77

Step 2:
If we divide 86 by 77, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 77 from 86 leaves us with 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 77

Let's proceed to step 3:
96 divided by 77 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 19 after subtracting 77 from 96.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 77

Going ahead to step 4:
The number 77 fits into 197 2 times, leaving a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtracting 154 from 197 leaves us with 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 77

On to step 5:
433 divided by 77 is 5 with a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 1125.0
If we take 385 away from 433, we end up with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 77

Going ahead to step 6:
77 can be fit into 488 6 times, resulting in a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 11256.0
Deduct 462 from 488 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
260 divided by 77 is 3 with a remainder of 29.
The next digit of our result is 3. 
Result so far: 11256.3
If we subtract 231 from 260, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 8:
If we divide 290 by 77, we get 3 and a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 11256.33
Subtracting 231 from 290 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 11256.33, with a leftover of 0.059.
