78877654 divided by 273 
We want to divide 78877654 by 273.

Moving on to step 1:
If we divide 7 by 273, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 273

Going ahead to step 2:
If we divide 78 by 273, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 273

Going ahead to step 3:
273 goes into 788 2 times with a remainder of 242.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 546 from 788 and we're left with 242.
Append the next digit (7) from the dividend to 242 and continue with: 2427 / 273

Let's proceed to step 4:
2427 divided by 273 is 8 with a remainder of 243.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 2184 from 2427 to get 243.
Include the next digit (7) from the dividend after 243, then repeat: 2437 / 273

Let's proceed to step 5:
2437 divided by 273 is 8 with a remainder of 253.
Write down 8 as next digit of the result. 
Result so far: 288.0
Subtract 2184 from 2437 to get 253.
Grab the next digit (6) from the dividend, add it to 253, then carry on: 2536 / 273

Advancing to step 6:
2536 divided by 273 is 9 with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 2889.0
If we subtract 2457 from 2536, we get 79.
Append the next digit (5) from the dividend to 79 and continue with: 795 / 273

Step 7:
273 can be fit into 795 2 times, resulting in a remainder of 249.
Put 2 as the next digit of the answer. 
Result so far: 28892.0
The remainder is 249 after subtracting 546 from 795.
Take the next digit (4) from the dividend and append it to 249, then repeat: 2494 / 273

Advancing to step 8:
When dividing 2494 by 273, we get 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 288929.0
The remainder is 37 after subtracting 2457 from 2494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
273 can be fit into 370 1 times, resulting in a remainder of 97.
Use 1 as the next digit of our solution. 
Result so far: 288929.1
If we subtract 273 from 370, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 10:
The number 273 fits into 970 3 times, leaving a remainder of 151.
Use 3 as the next digit of our solution. 
Result so far: 288929.13
If we take 819 away from 970, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 11:
The number 273 fits into 1510 5 times, leaving a remainder of 145.
The next digit of our result is 5. 
Result so far: 288929.135
Deduct 1365 from 1510 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 12:
273 goes into 1450 5 times with a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 288929.1355
The remainder is 85 after subtracting 1365 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 288929.1355, with a leftover of 0.00085.
