We look at the division of 780521 by 11 
We want to figure out the number of times 780521 can be divided by 11.

Moving on to step 1:
11 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 11

Advancing to step 2:
11 can be fit into 78 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 1 after subtracting 77 from 78.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 11

On to step 3:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 11

Step 4:
11 can be fit into 105 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 709.0
Subtract 99 from 105 to get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 11

Going ahead to step 5:
11 can be fit into 62 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 7095.0
If we subtract 55 from 62, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 11

Moving on to step 6:
When dividing 71 by 11, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 70956.0
The remainder is 5 after subtracting 66 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
When dividing 50 by 11, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 70956.4
If we take 44 away from 50, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
60 divided by 11 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 70956.45
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 70956.454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
60 divided by 11 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 70956.4545
Subtract 55 from 60 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
When dividing 50 by 11, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 70956.45454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 70956.454545
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
50 divided by 11 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 70956.4545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 70956.45454545
If we take 55 away from 60, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 70956.45454545, and the remainder is 5e-09.
