If we divide 77 by 990, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 990

Going ahead to step 3:
When dividing 776 by 990, we get 0 with a remainder of 776.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 776 to get 776.
Grab the next digit (6) from the dividend, add it to 776, then carry on: 7766 / 990

Let's proceed to step 4:
The number 990 fits into 7766 7 times, leaving a remainder of 836.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 6930 from 7766, we get 836.
Grab the next digit (9) from the dividend, add it to 836, then carry on: 8369 / 990

On to step 5:
When dividing 8369 by 990, we get 8 with a remainder of 449.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 7920 from 8369 to get 449.
Grab the next digit (2) from the dividend, add it to 449, then carry on: 4492 / 990

Let's proceed to step 6:
4492 divided by 990 is 4 with a remainder of 532.
Use 4 as the next digit of our solution. 
Result so far: 784.0
Deduct 3960 from 4492 and we're left with 532.
Append the next digit (5) from the dividend to 532 and continue with: 5325 / 990

Going ahead to step 7:
When dividing 5325 by 990, we get 5 with a remainder of 375.
Record the quotient 5 as the next digit in the result. 
Result so far: 7845.0
If we subtract 4950 from 5325, we get 375.
Include the next digit (7) from the dividend after 375, then repeat: 3757 / 990

Let's proceed to step 8:
990 can be fit into 3757 3 times, resulting in a remainder of 787.
The number 3 becomes the next digit in our result. 
Result so far: 78453.0
Subtracting 2970 from 3757 leaves us with 787.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7870, and continue the process.

Let's proceed to step 9:
990 goes into 7870 7 times with a remainder of 940.
Put 7 as the next digit of the answer. 
Result so far: 78453.7
If we subtract 6930 from 7870, we get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Going ahead to step 10:
9400 divided by 990 is 9 with a remainder of 490.
Write down 9 as next digit of the result. 
Result so far: 78453.79
Subtracting 8910 from 9400 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 11:
The number 990 fits into 4900 4 times, leaving a remainder of 940.
Write down 4 as next digit of the result. 
Result so far: 78453.794
Deduct 3960 from 4900 and we're left with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Advancing to step 12:
9400 divided by 990 is 9 with a remainder of 490.
Write down 9 as next digit of the result. 
Result so far: 78453.7949
Deduct 8910 from 9400 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 13:
When dividing 4900 by 990, we get 4 with a remainder of 940.
Put 4 as the next digit of the answer. 
Result so far: 78453.79494
Subtracting 3960 from 4900 leaves us with 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

On to step 14:
When dividing 9400 by 990, we get 9 with a remainder of 490.
The next digit of our result is 9. 
Result so far: 78453.794949
If we subtract 8910 from 9400, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 15:
990 goes into 4900 4 times with a remainder of 940.
The number 4 becomes the next digit in our result. 
Result so far: 78453.7949494
The remainder is 940 after subtracting 3960 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Going ahead to step 16:
The number 990 fits into 9400 9 times, leaving a remainder of 490.
Put 9 as the next digit of the answer. 
Result so far: 78453.79494949
If we take 8910 away from 9400, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

After the division, we end up with 78453.79494949 and a remainder of 4.9e-07.
