81846609 ÷ 780 
Our goal is to divide 81846609 by 780.

Let's proceed to 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.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 780

Going ahead to step 2:
When dividing 81 by 780, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 780

Moving on to step 3:
If we divide 818 by 780, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 780 from 818 and we're left with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 780

On to step 4:
780 can be fit into 384 0 times, resulting in a remainder of 384.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 384 leaves us with 384.
Append the next digit (6) from the dividend to 384 and continue with: 3846 / 780

Going ahead to step 5:
780 goes into 3846 4 times with a remainder of 726.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtract 3120 from 3846 to get 726.
Fetch the next digit (6) from the dividend, attach it to 726 and continue: 7266 / 780

Let's proceed to step 6:
The number 780 fits into 7266 9 times, leaving a remainder of 246.
Record the quotient 9 as the next digit in the result. 
Result so far: 1049.0
Subtracting 7020 from 7266 leaves us with 246.
Grab the next digit (0) from the dividend, add it to 246, then carry on: 2460 / 780

Going ahead to step 7:
When dividing 2460 by 780, we get 3 with a remainder of 120.
The next digit of our result is 3. 
Result so far: 10493.0
Subtract 2340 from 2460 to get 120.
Grab the next digit (9) from the dividend, add it to 120, then carry on: 1209 / 780

Going ahead to step 8:
The number 780 fits into 1209 1 times, leaving a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 104931.0
The remainder is 429 after subtracting 780 from 1209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Going ahead to step 9:
If we divide 4290 by 780, we get 5 and a remainder of 390.
Record the quotient 5 as the next digit in the result. 
Result so far: 104931.5
Subtracting 3900 from 4290 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
3900 divided by 780 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 104931.55
Subtract 3900 from 3900 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 104931.55 with a balance of 0.0.
