43878980 divided by 780 
We want to divide 43878980 by 780.

Moving on to step 1:
If we divide 4 by 780, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 780

Advancing to step 2:
43 divided by 780 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 780

Going ahead to step 3:
When dividing 438 by 780, we get 0 with a remainder of 438.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 438 and we're left with 438.
Bring next digit (7) of the dividend behind the 438 and repeat the process: 4387 / 780

Step 4:
780 goes into 4387 5 times with a remainder of 487.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 487 after subtracting 3900 from 4387.
Bring next digit (8) of the dividend behind the 487 and repeat the process: 4878 / 780

On to step 5:
When dividing 4878 by 780, we get 6 with a remainder of 198.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 4680 from 4878 leaves us with 198.
Append the next digit (9) from the dividend to 198 and continue with: 1989 / 780

Advancing to step 6:
When dividing 1989 by 780, we get 2 with a remainder of 429.
Use 2 as the next digit of our solution. 
Result so far: 562.0
Deduct 1560 from 1989 and we're left with 429.
Append the next digit (8) from the dividend to 429 and continue with: 4298 / 780

Advancing to step 7:
4298 divided by 780 is 5 with a remainder of 398.
Record the quotient 5 as the next digit in the result. 
Result so far: 5625.0
Deduct 3900 from 4298 and we're left with 398.
Bring next digit (0) of the dividend behind the 398 and repeat the process: 3980 / 780

Moving on to step 8:
3980 divided by 780 is 5 with a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 56255.0
If we subtract 3900 from 3980, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
780 can be fit into 800 1 times, resulting in a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 56255.1
Deduct 780 from 800 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
If we divide 200 by 780, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 56255.1
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
780 can be fit into 2000 2 times, resulting in a remainder of 440.
Write down 2 as next digit of the result. 
Result so far: 56255.102
Subtract 1560 from 2000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 12:
780 goes into 4400 5 times with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 56255.1025
Deduct 3900 from 4400 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 13:
When dividing 5000 by 780, we get 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 56255.10256
If we take 4680 away from 5000, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 14:
The number 780 fits into 3200 4 times, leaving a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 56255.102564
The remainder is 80 after subtracting 3120 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
If we divide 800 by 780, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 56255.1025641
If we take 780 away from 800, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 16:
If we divide 200 by 780, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 56255.1025641
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 56255.1025641, with a leftover of 2e-07.
