We look at the division of 305303 by 77 
We're looking to find how many times 77 goes into 305303.

On to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 77

On to step 2:
When dividing 30 by 77, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 77

Let's proceed to step 3:
305 divided by 77 is 3 with a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 231 away from 305, we end up with 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 77

Step 4:
743 divided by 77 is 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 693 from 743, we get 50.
Bring next digit (0) of the dividend behind the 50 and repeat the process: 500 / 77

Step 5:
500 divided by 77 is 6 with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 396.0
If we take 462 away from 500, we end up with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 77

Advancing to step 6:
383 divided by 77 is 4 with a remainder of 75.
The number 4 becomes the next digit in our result. 
Result so far: 3964.0
Subtracting 308 from 383 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
If we divide 750 by 77, we get 9 and a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 3964.9
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 8:
77 can be fit into 570 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 3964.97
Subtract 539 from 570 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
The number 77 fits into 310 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 3964.974
Subtracting 308 from 310 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 77, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3964.974
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
200 divided by 77 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 3964.97402
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
460 divided by 77 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3964.974025
Subtract 385 from 460 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
If we divide 750 by 77, we get 9 and a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 3964.9740259
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 14:
When dividing 570 by 77, we get 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 3964.97402597
The remainder is 31 after subtracting 539 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 3964.97402597 with a remaining 3.1e-08.
