81634108 divided by 780 
Let's see how many times 780 fits into 81634108.

Step 1:
8 divided by 780 is 0 with 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.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 780

Going ahead to step 2:
81 divided by 780 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 780

On to step 3:
780 can be fit into 816 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 780 from 816, we get 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 780

Step 4:
363 divided by 780 is 0 with a remainder of 363.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 363, we end up with 363.
Take the next digit (4) from the dividend and append it to 363, then repeat: 3634 / 780

On to step 5:
If we divide 3634 by 780, we get 4 and a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we subtract 3120 from 3634, we get 514.
Take the next digit (1) from the dividend and append it to 514, then repeat: 5141 / 780

Let's proceed to step 6:
780 can be fit into 5141 6 times, resulting in a remainder of 461.
The number 6 becomes the next digit in our result. 
Result so far: 1046.0
Subtract 4680 from 5141 to get 461.
Fetch the next digit (0) from the dividend, attach it to 461 and continue: 4610 / 780

Advancing to step 7:
The number 780 fits into 4610 5 times, leaving a remainder of 710.
Put 5 as the next digit of the answer. 
Result so far: 10465.0
If we subtract 3900 from 4610, we get 710.
Append the next digit (8) from the dividend to 710 and continue with: 7108 / 780

Advancing to step 8:
780 goes into 7108 9 times with a remainder of 88.
The next digit of our result is 9. 
Result so far: 104659.0
Subtracting 7020 from 7108 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 9:
When dividing 880 by 780, we get 1 with a remainder of 100.
Record the quotient 1 as the next digit in the result. 
Result so far: 104659.1
If we take 780 away from 880, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
780 can be fit into 1000 1 times, resulting in a remainder of 220.
Put 1 as the next digit of the answer. 
Result so far: 104659.11
Subtracting 780 from 1000 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 104659.11 and a remainder of 0.22.
