991049 ÷ 77 
Let's see how many times 77 fits into 991049.

Step 1:
77 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 77

Going ahead to step 2:
77 can be fit into 99 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 99 to get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 77

Advancing to step 3:
221 divided by 77 is 2 with a remainder of 67.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 67 after subtracting 154 from 221.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 77

Moving on to step 4:
When dividing 670 by 77, we get 8 with a remainder of 54.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 616 from 670 leaves us with 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 77

On to step 5:
544 divided by 77 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1287.0
If we subtract 539 from 544, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 77

On to step 6:
If we divide 59 by 77, we get 0 and a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 12870.0
The remainder is 59 after subtracting 0 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
590 divided by 77 is 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 12870.7
If we take 539 away from 590, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 8:
When dividing 510 by 77, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 12870.76
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
77 can be fit into 480 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 12870.766
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 12870.766 with a remaining 0.0018.
