Let's divide 78528880 by 11
Let's see how many times 11 fits into 78528880.

Advancing to step 1:
When dividing 7 by 11, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 11

On to step 2:
The number 11 fits into 78 7 times, leaving 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.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 11

Going ahead to step 3:
When dividing 15 by 11, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 11 away from 15, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 11

Going ahead to step 4:
11 goes into 42 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 713.0
Subtract 33 from 42 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 11

Step 5:
11 can be fit into 98 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 7138.0
Subtract 88 from 98 to get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 11

Let's proceed to step 6:
108 divided by 11 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 71389.0
The remainder is 9 after subtracting 99 from 108.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 11

On to step 7:
If we divide 98 by 11, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 713898.0
Subtracting 88 from 98 leaves us with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 11

On to step 8:
If we divide 100 by 11, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7138989.0
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
11 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7138989.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 11, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7138989.09
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
10 divided by 11 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7138989.09
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
The number 11 fits into 100 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 7138989.0909
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
10 divided by 11 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7138989.0909
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
100 divided by 11 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7138989.090909
If we take 99 away from 100, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 15:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7138989.090909
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 16:
When dividing 100 by 11, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 7138989.09090909
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 7138989.09090909 with a remainder of 1e-09.
