We look at the division of 777855 by 8 
Let's see how many times 8 fits into 777855.

On to step 1:
7 divided by 8 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 8

Going ahead to step 2:
The number 8 fits into 77 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 72 away from 77, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 8

Moving on to step 3:
When dividing 57 by 8, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 56 from 57 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 8

Going ahead to step 4:
If we divide 18 by 8, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 972.0
Subtracting 16 from 18 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 8

Moving on to step 5:
If we divide 25 by 8, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 9723.0
Subtract 24 from 25 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 8

Let's proceed to step 6:
The number 8 fits into 15 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 97231.0
Deduct 8 from 15 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 8 fits into 70 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 97231.8
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 97231.87
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 97231.875
If we subtract 40 from 40, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 97231.875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 97231.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 97231.875, and the remainder is 0.0.
