We look at the division of 120781 by 8 
Let's see how many times 8 fits into 120781.

Advancing to step 1:
8 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 8

Step 2:
If we divide 12 by 8, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 8 from 12 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 8

Let's proceed to step 3:
8 goes into 40 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15.0
If we take 40 away from 40, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 8

Advancing to step 4:
8 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 8

On to step 5:
78 divided by 8 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1509.0
Deduct 72 from 78 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 8

Going ahead to step 6:
If we divide 61 by 8, we get 7 and a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 15097.0
If we take 56 away from 61, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 8, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 15097.6
The remainder is 2 after subtracting 48 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 8 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15097.62
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15097.625
Subtracting 40 from 40 leaves us 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.

Advancing to step 10:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15097.625
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.

Let's proceed to step 11:
0 divided by 8 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15097.625
Subtracting 0 from 0 leaves us 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 final result is 15097.625 with a remainder of 0.0.
