We divide 80378555 by 560
Our goal is to divide 80378555 by 560.

Going ahead to step 1:
560 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 560

Advancing to step 2:
The number 560 fits into 80 0 times, leaving 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.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 560

Moving on to step 3:
560 goes into 803 1 times with a remainder of 243.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 560 from 803, we get 243.
Bring next digit (7) of the dividend behind the 243 and repeat the process: 2437 / 560

Moving on to step 4:
2437 divided by 560 is 4 with a remainder of 197.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 197 after subtracting 2240 from 2437.
Include the next digit (8) from the dividend after 197, then repeat: 1978 / 560

Step 5:
560 can be fit into 1978 3 times, resulting in a remainder of 298.
The next digit of our result is 3. 
Result so far: 143.0
Deduct 1680 from 1978 and we're left with 298.
Grab the next digit (5) from the dividend, add it to 298, then carry on: 2985 / 560

Let's proceed to step 6:
When dividing 2985 by 560, we get 5 with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 1435.0
The remainder is 185 after subtracting 2800 from 2985.
Fetch the next digit (5) from the dividend, attach it to 185 and continue: 1855 / 560

Moving on to step 7:
560 goes into 1855 3 times with a remainder of 175.
Write down 3 as next digit of the result. 
Result so far: 14353.0
If we take 1680 away from 1855, we end up with 175.
Take the next digit (5) from the dividend and append it to 175, then repeat: 1755 / 560

Let's proceed to step 8:
560 can be fit into 1755 3 times, resulting in a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 143533.0
If we subtract 1680 from 1755, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
The number 560 fits into 750 1 times, leaving a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 143533.1
If we subtract 560 from 750, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 10:
560 can be fit into 1900 3 times, resulting in a remainder of 220.
Put 3 as the next digit of the answer. 
Result so far: 143533.13
Subtracting 1680 from 1900 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.

Step 11:
If we divide 2200 by 560, we get 3 and a remainder of 520.
Write down 3 as next digit of the result. 
Result so far: 143533.133
If we take 1680 away from 2200, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The quotient of the division is 143533.133, and the remainder is 0.052.
