285977 ÷ 77 
Our goal is to divide 285977 by 77.

Step 1:
When dividing 2 by 77, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 77

Going ahead to step 2:
If we divide 28 by 77, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 77

Going ahead to step 3:
When dividing 285 by 77, we get 3 with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 231 from 285 to get 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 77

Moving on to step 4:
77 can be fit into 549 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtracting 539 from 549 leaves us with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 77

Moving on to step 5:
When dividing 107 by 77, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 371.0
If we subtract 77 from 107, we get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 77

Advancing to step 6:
When dividing 307 by 77, we get 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 3713.0
If we subtract 231 from 307, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 7:
760 divided by 77 is 9 with a remainder of 67.
The next digit of our result is 9. 
Result so far: 3713.9
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 8:
When dividing 670 by 77, we get 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 3713.98
Deduct 616 from 670 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
77 goes into 540 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 3713.987
Subtracting 539 from 540 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3713.987
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 77, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 3713.98701
Deduct 77 from 100 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
If we divide 230 by 77, we get 2 and a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 3713.987012
Subtracting 154 from 230 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
If we divide 760 by 77, we get 9 and a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 3713.9870129
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 14:
77 can be fit into 670 8 times, resulting in a remainder of 54.
The next digit of our result is 8. 
Result so far: 3713.98701298
Subtracting 616 from 670 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 3713.98701298 and a remainder of 5.4e-08.
