We divide 80476855 by 780
Our goal is to divide 80476855 by 780.

Step 1:
780 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 780

Advancing to step 2:
When dividing 80 by 780, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 780

Advancing to step 3:
780 can be fit into 804 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 780 from 804 to get 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 780

On to step 4:
780 can be fit into 247 0 times, resulting in a remainder of 247.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 247 to get 247.
Append the next digit (6) from the dividend to 247 and continue with: 2476 / 780

Step 5:
If we divide 2476 by 780, we get 3 and a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 103.0
Deduct 2340 from 2476 and we're left with 136.
Take the next digit (8) from the dividend and append it to 136, then repeat: 1368 / 780

Step 6:
When dividing 1368 by 780, we get 1 with a remainder of 588.
Use 1 as the next digit of our solution. 
Result so far: 1031.0
Subtracting 780 from 1368 leaves us with 588.
Grab the next digit (5) from the dividend, add it to 588, then carry on: 5885 / 780

Let's proceed to step 7:
780 goes into 5885 7 times with a remainder of 425.
Use 7 as the next digit of our solution. 
Result so far: 10317.0
Subtract 5460 from 5885 to get 425.
Bring next digit (5) of the dividend behind the 425 and repeat the process: 4255 / 780

Going ahead to step 8:
The number 780 fits into 4255 5 times, leaving a remainder of 355.
Write down 5 as next digit of the result. 
Result so far: 103175.0
Deduct 3900 from 4255 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 9:
The number 780 fits into 3550 4 times, leaving a remainder of 430.
Put 4 as the next digit of the answer. 
Result so far: 103175.4
The remainder is 430 after subtracting 3120 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
780 can be fit into 4300 5 times, resulting in a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 103175.45
Subtracting 3900 from 4300 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
780 can be fit into 4000 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 103175.455
Deduct 3900 from 4000 and we're left 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.

The final outcome is 103175.455, with a leftover of 0.01.
