Let's divide 303579 by 77
Let's see how many times 77 fits into 303579.

Advancing to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 77

Moving on to step 2:
If we divide 30 by 77, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 77

On to step 3:
77 can be fit into 303 3 times, resulting in a remainder of 72.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 231 from 303 to get 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 77

Step 4:
When dividing 725 by 77, we get 9 with a remainder of 32.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 693 from 725 to get 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 77

Let's proceed to step 5:
When dividing 327 by 77, we get 4 with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
The remainder is 19 after subtracting 308 from 327.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 77

On to step 6:
When dividing 199 by 77, we get 2 with a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 3942.0
Subtract 154 from 199 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
77 goes into 450 5 times with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 3942.5
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.

On to step 8:
77 goes into 650 8 times with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 3942.58
Deduct 616 from 650 and we're left 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.

Let's proceed to step 9:
77 goes into 340 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 3942.584
If we subtract 308 from 340, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
77 goes into 320 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 3942.5844
If we take 308 away from 320, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 3942.5844, and the remainder is 0.00012.
