13113791 divided by 720 
We want to figure out the number of times 13113791 can be divided by 720.

Going ahead to step 1:
The number 720 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 720

Moving on to step 2:
When dividing 13 by 720, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 720

Going ahead to step 3:
720 can be fit into 131 0 times, resulting in a remainder of 131.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 131 to get 131.
Take the next digit (1) from the dividend and append it to 131, then repeat: 1311 / 720

Going ahead to step 4:
If we divide 1311 by 720, we get 1 and a remainder of 591.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 591 after subtracting 720 from 1311.
Grab the next digit (3) from the dividend, add it to 591, then carry on: 5913 / 720

Step 5:
720 goes into 5913 8 times with a remainder of 153.
The next digit of our result is 8. 
Result so far: 18.0
If we take 5760 away from 5913, we end up with 153.
Take the next digit (7) from the dividend and append it to 153, then repeat: 1537 / 720

Step 6:
When dividing 1537 by 720, we get 2 with a remainder of 97.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
Deduct 1440 from 1537 and we're left with 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 720

Moving on to step 7:
When dividing 979 by 720, we get 1 with a remainder of 259.
The next digit of our result is 1. 
Result so far: 1821.0
Subtract 720 from 979 to get 259.
Grab the next digit (1) from the dividend, add it to 259, then carry on: 2591 / 720

Advancing to step 8:
If we divide 2591 by 720, we get 3 and a remainder of 431.
Record the quotient 3 as the next digit in the result. 
Result so far: 18213.0
If we take 2160 away from 2591, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Advancing to step 9:
When dividing 4310 by 720, we get 5 with a remainder of 710.
The number 5 becomes the next digit in our result. 
Result so far: 18213.5
If we subtract 3600 from 4310, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 10:
720 goes into 7100 9 times with a remainder of 620.
Write down 9 as next digit of the result. 
Result so far: 18213.59
Subtract 6480 from 7100 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 11:
6200 divided by 720 is 8 with a remainder of 440.
Use 8 as the next digit of our solution. 
Result so far: 18213.598
The remainder is 440 after subtracting 5760 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 12:
720 can be fit into 4400 6 times, resulting in a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 18213.5986
The remainder is 80 after subtracting 4320 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
The number 720 fits into 800 1 times, leaving a remainder of 80.
The next digit of our result is 1. 
Result so far: 18213.59861
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 14:
720 goes into 800 1 times with a remainder of 80.
Record the quotient 1 as the next digit in the result. 
Result so far: 18213.598611
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 18213.598611, with a leftover of 8e-06.
