We're dividing 864755 by 77 
We're looking to find how many times 77 goes into 864755.

Moving on to step 1:
8 divided by 77 is 0 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.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 77

On to step 2:
86 divided by 77 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 77 from 86 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 77

Advancing to step 3:
77 goes into 94 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 77 from 94 and we're left with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 77

Let's proceed to step 4:
177 divided by 77 is 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 112.0
The remainder is 23 after subtracting 154 from 177.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 77

Step 5:
If we divide 235 by 77, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 1123.0
If we take 231 away from 235, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 77

On to step 6:
77 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 11230.0
Subtracting 0 from 45 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
450 divided by 77 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 11230.5
If we take 385 away from 450, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
77 can be fit into 650 8 times, resulting in a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 11230.58
Subtracting 616 from 650 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
340 divided by 77 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 11230.584
Deduct 308 from 340 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 77, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 11230.5844
The remainder is 12 after subtracting 308 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 11230.5844 with a remaining 0.00012.
