55777879 ÷ 720 
We want to figure out the number of times 55777879 can be divided by 720.

On to step 1:
720 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 720

Going ahead to step 2:
When dividing 55 by 720, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 720

Step 3:
720 goes into 557 0 times with a remainder of 557.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 557 and we're left with 557.
Include the next digit (7) from the dividend after 557, then repeat: 5577 / 720

Advancing to step 4:
When dividing 5577 by 720, we get 7 with a remainder of 537.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 537 after subtracting 5040 from 5577.
Grab the next digit (7) from the dividend, add it to 537, then carry on: 5377 / 720

On to step 5:
The number 720 fits into 5377 7 times, leaving a remainder of 337.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 5040 from 5377 leaves us with 337.
Grab the next digit (8) from the dividend, add it to 337, then carry on: 3378 / 720

Advancing to step 6:
The number 720 fits into 3378 4 times, leaving a remainder of 498.
Put 4 as the next digit of the answer. 
Result so far: 774.0
If we subtract 2880 from 3378, we get 498.
Bring next digit (7) of the dividend behind the 498 and repeat the process: 4987 / 720

Let's proceed to step 7:
720 goes into 4987 6 times with a remainder of 667.
Record the quotient 6 as the next digit in the result. 
Result so far: 7746.0
If we take 4320 away from 4987, we end up with 667.
Fetch the next digit (9) from the dividend, attach it to 667 and continue: 6679 / 720

Going ahead to step 8:
If we divide 6679 by 720, we get 9 and a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 77469.0
Deduct 6480 from 6679 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 9:
When dividing 1990 by 720, we get 2 with a remainder of 550.
Put 2 as the next digit of the answer. 
Result so far: 77469.2
Subtracting 1440 from 1990 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
When dividing 5500 by 720, we get 7 with a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 77469.27
The remainder is 460 after subtracting 5040 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 11:
720 can be fit into 4600 6 times, resulting in a remainder of 280.
Write down 6 as next digit of the result. 
Result so far: 77469.276
The remainder is 280 after subtracting 4320 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
When dividing 2800 by 720, we get 3 with a remainder of 640.
Use 3 as the next digit of our solution. 
Result so far: 77469.2763
The remainder is 640 after subtracting 2160 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 13:
720 goes into 6400 8 times with a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 77469.27638
The remainder is 640 after subtracting 5760 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 14:
When dividing 6400 by 720, we get 8 with a remainder of 640.
Record the quotient 8 as the next digit in the result. 
Result so far: 77469.276388
If we subtract 5760 from 6400, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

In conclusion, the division gives 77469.276388 with a balance of 6.4e-05.
