We're dividing 7900 by 11 
Let's see how many times 11 fits into 7900.

Advancing to step 1:
If we divide 7 by 11, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 11

Step 2:
When dividing 79 by 11, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 2 after subtracting 77 from 79.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 11

On to step 3:
If we divide 20 by 11, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 9 after subtracting 11 from 20.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 11

Moving on to step 4:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 718.0
If we subtract 88 from 90, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 5:
The number 11 fits into 20 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 718.1
If we subtract 11 from 20, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 6:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 718.18
If we subtract 88 from 90, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 11, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 718.181
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
90 divided by 11 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 718.1818
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
If we divide 20 by 11, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 718.18181
Deduct 11 from 20 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
The number 11 fits into 90 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 718.181818
If we subtract 88 from 90, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
If we divide 20 by 11, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 718.1818181
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
90 divided by 11 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 718.18181818
Deduct 88 from 90 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 718.18181818 with a remainder of 2e-09.
