We're dividing 80719839 by 11 
We want to divide 80719839 by 11.

Going ahead to step 1:
The number 11 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 11

On to step 2:
When dividing 80 by 11, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 77 from 80, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 11

Going ahead to step 3:
11 can be fit into 37 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we subtract 33 from 37, we get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 11

Advancing to step 4:
11 goes into 41 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 733.0
Subtract 33 from 41 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 11

Advancing to step 5:
When dividing 89 by 11, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 7338.0
If we take 88 away from 89, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 11

Moving on to step 6:
11 goes into 18 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 73381.0
The remainder is 7 after subtracting 11 from 18.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 11

Let's proceed to step 7:
73 divided by 11 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 733816.0
Deduct 66 from 73 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 11

Moving on to step 8:
If we divide 79 by 11, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 7338167.0
The remainder is 2 after subtracting 77 from 79.
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:
20 divided by 11 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 7338167.1
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 10:
11 goes into 90 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7338167.18
If we take 88 away from 90, we end up 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.

On to step 11:
When dividing 20 by 11, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 7338167.181
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 12:
90 divided by 11 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 7338167.1818
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 13:
When dividing 20 by 11, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 7338167.18181
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 14:
If we divide 90 by 11, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 7338167.181818
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.

Step 15:
The number 11 fits into 20 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 7338167.1818181
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.

Going ahead to step 16:
11 can be fit into 90 8 times, resulting in a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 7338167.18181818
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.

After the division, we end up with 7338167.18181818 and a remainder of 2e-09.
