We're dividing 98580557 by 720 
Our goal is to divide 98580557 by 720.

On to step 1:
The number 720 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 720

On to step 2:
98 divided by 720 is 0 with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Include the next digit (5) from the dividend after 98, then repeat: 985 / 720

On to step 3:
If we divide 985 by 720, we get 1 and a remainder of 265.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 720 away from 985, we end up with 265.
Include the next digit (8) from the dividend after 265, then repeat: 2658 / 720

On to step 4:
720 goes into 2658 3 times with a remainder of 498.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 2160 from 2658, we get 498.
Fetch the next digit (0) from the dividend, attach it to 498 and continue: 4980 / 720

Going ahead to step 5:
720 goes into 4980 6 times with a remainder of 660.
Put 6 as the next digit of the answer. 
Result so far: 136.0
Subtracting 4320 from 4980 leaves us with 660.
Bring next digit (5) of the dividend behind the 660 and repeat the process: 6605 / 720

Going ahead to step 6:
If we divide 6605 by 720, we get 9 and a remainder of 125.
Write down 9 as next digit of the result. 
Result so far: 1369.0
Subtract 6480 from 6605 to get 125.
Fetch the next digit (5) from the dividend, attach it to 125 and continue: 1255 / 720

Let's proceed to step 7:
If we divide 1255 by 720, we get 1 and a remainder of 535.
The next digit of our result is 1. 
Result so far: 13691.0
If we take 720 away from 1255, we end up with 535.
Include the next digit (7) from the dividend after 535, then repeat: 5357 / 720

Step 8:
When dividing 5357 by 720, we get 7 with a remainder of 317.
Write down 7 as next digit of the result. 
Result so far: 136917.0
If we subtract 5040 from 5357, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 9:
720 can be fit into 3170 4 times, resulting in a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 136917.4
The remainder is 290 after subtracting 2880 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
When dividing 2900 by 720, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 136917.44
Subtracting 2880 from 2900 leaves us 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.

The final outcome is 136917.44, with a leftover of 0.02.
