We're dividing 3057097 by 770 
We want to figure out the number of times 3057097 can be divided by 770.

Going ahead to step 1:
770 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 770

Moving on to step 2:
770 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 770

Let's proceed to step 3:
770 can be fit into 305 0 times, resulting in a remainder of 305.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 305, we get 305.
Include the next digit (7) from the dividend after 305, then repeat: 3057 / 770

On to step 4:
The number 770 fits into 3057 3 times, leaving a remainder of 747.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 2310 away from 3057, we end up with 747.
Append the next digit (0) from the dividend to 747 and continue with: 7470 / 770

Let's proceed to step 5:
The number 770 fits into 7470 9 times, leaving a remainder of 540.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 6930 from 7470 leaves us with 540.
Bring next digit (9) of the dividend behind the 540 and repeat the process: 5409 / 770

Step 6:
If we divide 5409 by 770, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 397.0
Subtract 5390 from 5409 to get 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 770

On to step 7:
770 can be fit into 197 0 times, resulting in a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 3970.0
Subtracting 0 from 197 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 8:
The number 770 fits into 1970 2 times, leaving a remainder of 430.
Write down 2 as next digit of the result. 
Result so far: 3970.2
If we subtract 1540 from 1970, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 9:
The number 770 fits into 4300 5 times, leaving a remainder of 450.
The next digit of our result is 5. 
Result so far: 3970.25
Subtracting 3850 from 4300 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
770 goes into 4500 5 times with a remainder of 650.
The next digit of our result is 5. 
Result so far: 3970.255
Subtracting 3850 from 4500 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

In conclusion, the division gives 3970.255 with a balance of 0.065.
