80921102 divided by 781 
We want to figure out the number of times 80921102 can be divided by 781.

On to step 1:
When dividing 8 by 781, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 781

Going ahead to step 2:
781 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 781

Advancing to step 3:
781 goes into 809 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 28 after subtracting 781 from 809.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 781

Moving on to step 4:
When dividing 282 by 781, we get 0 with a remainder of 282.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 282 after subtracting 0 from 282.
Fetch the next digit (1) from the dividend, attach it to 282 and continue: 2821 / 781

On to step 5:
When dividing 2821 by 781, we get 3 with a remainder of 478.
Write down 3 as next digit of the result. 
Result so far: 103.0
The remainder is 478 after subtracting 2343 from 2821.
Fetch the next digit (1) from the dividend, attach it to 478 and continue: 4781 / 781

Step 6:
4781 divided by 781 is 6 with a remainder of 95.
Write down 6 as next digit of the result. 
Result so far: 1036.0
The remainder is 95 after subtracting 4686 from 4781.
Include the next digit (0) from the dividend after 95, then repeat: 950 / 781

Let's proceed to step 7:
781 can be fit into 950 1 times, resulting in a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 10361.0
Deduct 781 from 950 and we're left with 169.
Take the next digit (2) from the dividend and append it to 169, then repeat: 1692 / 781

Advancing to step 8:
781 can be fit into 1692 2 times, resulting in a remainder of 130.
Record the quotient 2 as the next digit in the result. 
Result so far: 103612.0
The remainder is 130 after subtracting 1562 from 1692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 9:
781 goes into 1300 1 times with a remainder of 519.
Record the quotient 1 as the next digit in the result. 
Result so far: 103612.1
If we subtract 781 from 1300, we get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Advancing to step 10:
When dividing 5190 by 781, we get 6 with a remainder of 504.
The number 6 becomes the next digit in our result. 
Result so far: 103612.16
If we subtract 4686 from 5190, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 11:
5040 divided by 781 is 6 with a remainder of 354.
Write down 6 as next digit of the result. 
Result so far: 103612.166
Subtracting 4686 from 5040 leaves us with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The final outcome is 103612.166, with a leftover of 0.0354.
