13318395 ÷ 721 
We're looking to find how many times 721 goes into 13318395.

Step 1:
1 divided by 721 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 721

Let's proceed to step 2:
If we divide 13 by 721, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 721

Step 3:
721 can be fit into 133 0 times, resulting in a remainder of 133.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 133, we get 133.
Include the next digit (1) from the dividend after 133, then repeat: 1331 / 721

On to step 4:
The number 721 fits into 1331 1 times, leaving a remainder of 610.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 721 from 1331, we get 610.
Bring next digit (8) of the dividend behind the 610 and repeat the process: 6108 / 721

Moving on to step 5:
If we divide 6108 by 721, we get 8 and a remainder of 340.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 340 after subtracting 5768 from 6108.
Bring next digit (3) of the dividend behind the 340 and repeat the process: 3403 / 721

Step 6:
When dividing 3403 by 721, we get 4 with a remainder of 519.
Put 4 as the next digit of the answer. 
Result so far: 184.0
The remainder is 519 after subtracting 2884 from 3403.
Bring next digit (9) of the dividend behind the 519 and repeat the process: 5199 / 721

Let's proceed to step 7:
When dividing 5199 by 721, we get 7 with a remainder of 152.
The number 7 becomes the next digit in our result. 
Result so far: 1847.0
Subtracting 5047 from 5199 leaves us with 152.
Bring next digit (5) of the dividend behind the 152 and repeat the process: 1525 / 721

Advancing to step 8:
When dividing 1525 by 721, we get 2 with a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 18472.0
The remainder is 83 after subtracting 1442 from 1525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 9:
If we divide 830 by 721, we get 1 and a remainder of 109.
Record the quotient 1 as the next digit in the result. 
Result so far: 18472.1
Subtracting 721 from 830 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 10:
721 goes into 1090 1 times with a remainder of 369.
The number 1 becomes the next digit in our result. 
Result so far: 18472.11
The remainder is 369 after subtracting 721 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

The final result is 18472.11 with a remainder of 0.369.
