We divide 81021019 by 779
Let's see how many times 779 fits into 81021019.

Moving on to step 1:
779 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 779

Going ahead to step 2:
779 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 779

Moving on to step 3:
When dividing 810 by 779, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 779 from 810 to get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 779

Let's proceed to step 4:
779 can be fit into 312 0 times, resulting in a remainder of 312.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 312 and we're left with 312.
Fetch the next digit (1) from the dividend, attach it to 312 and continue: 3121 / 779

Step 5:
If we divide 3121 by 779, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 5 after subtracting 3116 from 3121.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 779

Going ahead to step 6:
If we divide 50 by 779, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1040.0
If we subtract 0 from 50, we get 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 779

Advancing to step 7:
779 can be fit into 501 0 times, resulting in a remainder of 501.
The next digit of our result is 0. 
Result so far: 10400.0
Subtracting 0 from 501 leaves us with 501.
Grab the next digit (9) from the dividend, add it to 501, then carry on: 5019 / 779

Going ahead to step 8:
If we divide 5019 by 779, we get 6 and a remainder of 345.
Write down 6 as next digit of the result. 
Result so far: 104006.0
Deduct 4674 from 5019 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 9:
779 can be fit into 3450 4 times, resulting in a remainder of 334.
Record the quotient 4 as the next digit in the result. 
Result so far: 104006.4
If we take 3116 away from 3450, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 10:
3340 divided by 779 is 4 with a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 104006.44
The remainder is 224 after subtracting 3116 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final outcome is 104006.44, with a leftover of 0.224.
