Let's divide 991150 by 77
We want to figure out the number of times 991150 can be divided by 77.

Let's proceed to step 1:
77 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 77

Advancing to step 2:
77 goes into 99 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 77 from 99 to get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 77

On to step 3:
When dividing 221 by 77, we get 2 with a remainder of 67.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 154 from 221 to get 67.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 77

Step 4:
If we divide 671 by 77, we get 8 and a remainder of 55.
The next digit of our result is 8. 
Result so far: 128.0
Subtract 616 from 671 to get 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 77

Going ahead to step 5:
If we divide 555 by 77, we get 7 and a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 1287.0
Subtract 539 from 555 to get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 77

Advancing to step 6:
77 can be fit into 160 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 12872.0
The remainder is 6 after subtracting 154 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 77 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 12872.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 77, we get 7 and a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 12872.07
If we take 539 away from 600, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
77 can be fit into 610 7 times, resulting in a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 12872.077
Subtract 539 from 610 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 12872.077 with a remaining 0.0071.
