We look at the division of 99911430 by 720 
We want to divide 99911430 by 720.

Step 1:
720 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 720

Step 2:
When dividing 99 by 720, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 720

Step 3:
If we divide 999 by 720, we get 1 and a remainder of 279.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 720 from 999 leaves us with 279.
Append the next digit (1) from the dividend to 279 and continue with: 2791 / 720

Advancing to step 4:
720 goes into 2791 3 times with a remainder of 631.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 2160 away from 2791, we end up with 631.
Bring next digit (1) of the dividend behind the 631 and repeat the process: 6311 / 720

Advancing to step 5:
720 can be fit into 6311 8 times, resulting in a remainder of 551.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
If we take 5760 away from 6311, we end up with 551.
Fetch the next digit (4) from the dividend, attach it to 551 and continue: 5514 / 720

Let's proceed to step 6:
5514 divided by 720 is 7 with a remainder of 474.
Put 7 as the next digit of the answer. 
Result so far: 1387.0
Subtract 5040 from 5514 to get 474.
Grab the next digit (3) from the dividend, add it to 474, then carry on: 4743 / 720

Advancing to step 7:
4743 divided by 720 is 6 with a remainder of 423.
Use 6 as the next digit of our solution. 
Result so far: 13876.0
The remainder is 423 after subtracting 4320 from 4743.
Bring next digit (0) of the dividend behind the 423 and repeat the process: 4230 / 720

Moving on to step 8:
720 can be fit into 4230 5 times, resulting in a remainder of 630.
Write down 5 as next digit of the result. 
Result so far: 138765.0
If we take 3600 away from 4230, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 9:
720 goes into 6300 8 times with a remainder of 540.
Write down 8 as next digit of the result. 
Result so far: 138765.8
Subtracting 5760 from 6300 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 10:
720 goes into 5400 7 times with a remainder of 360.
The number 7 becomes the next digit in our result. 
Result so far: 138765.87
If we subtract 5040 from 5400, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 11:
3600 divided by 720 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 138765.875
If we subtract 3600 from 3600, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
0 divided by 720 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 138765.875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
720 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 138765.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 138765.875, with a leftover of 0.0.
