11979911 ÷ 797 
We want to figure out the number of times 11979911 can be divided by 797.

Moving on to step 1:
797 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 797

Going ahead to step 2:
11 divided by 797 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 797

Let's proceed to step 3:
119 divided by 797 is 0 with a remainder of 119.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 119 leaves us with 119.
Append the next digit (7) from the dividend to 119 and continue with: 1197 / 797

Moving on to step 4:
The number 797 fits into 1197 1 times, leaving a remainder of 400.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 797 away from 1197, we end up with 400.
Take the next digit (9) from the dividend and append it to 400, then repeat: 4009 / 797

Going ahead to step 5:
797 goes into 4009 5 times with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 3985 from 4009, we get 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 797

Advancing to step 6:
If we divide 249 by 797, we get 0 and a remainder of 249.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtracting 0 from 249 leaves us with 249.
Grab the next digit (1) from the dividend, add it to 249, then carry on: 2491 / 797

Going ahead to step 7:
797 goes into 2491 3 times with a remainder of 100.
The next digit of our result is 3. 
Result so far: 1503.0
The remainder is 100 after subtracting 2391 from 2491.
Append the next digit (1) from the dividend to 100 and continue with: 1001 / 797

Moving on to step 8:
797 can be fit into 1001 1 times, resulting in a remainder of 204.
Write down 1 as next digit of the result. 
Result so far: 15031.0
Deduct 797 from 1001 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 9:
797 can be fit into 2040 2 times, resulting in a remainder of 446.
Put 2 as the next digit of the answer. 
Result so far: 15031.2
Deduct 1594 from 2040 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 10:
If we divide 4460 by 797, we get 5 and a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 15031.25
Deduct 3985 from 4460 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 11:
When dividing 4750 by 797, we get 5 with a remainder of 765.
The next digit of our result is 5. 
Result so far: 15031.255
Deduct 3985 from 4750 and we're left with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

The final result is 15031.255 with a remainder of 0.0765.
