9141328 ÷ 720 
We want to figure out the number of times 9141328 can be divided by 720.

On to step 1:
720 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 720

Advancing to step 2:
720 goes into 91 0 times with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (4) from the dividend after 91, then repeat: 914 / 720

On to step 3:
If we divide 914 by 720, we get 1 and a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 720 from 914 leaves us with 194.
Take the next digit (1) from the dividend and append it to 194, then repeat: 1941 / 720

Going ahead to step 4:
When dividing 1941 by 720, we get 2 with a remainder of 501.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 501 after subtracting 1440 from 1941.
Append the next digit (3) from the dividend to 501 and continue with: 5013 / 720

Advancing to step 5:
720 goes into 5013 6 times with a remainder of 693.
Put 6 as the next digit of the answer. 
Result so far: 126.0
The remainder is 693 after subtracting 4320 from 5013.
Include the next digit (2) from the dividend after 693, then repeat: 6932 / 720

On to step 6:
720 goes into 6932 9 times with a remainder of 452.
Write down 9 as next digit of the result. 
Result so far: 1269.0
Deduct 6480 from 6932 and we're left with 452.
Fetch the next digit (8) from the dividend, attach it to 452 and continue: 4528 / 720

Going ahead to step 7:
720 can be fit into 4528 6 times, resulting in a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 12696.0
If we take 4320 away from 4528, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 8:
720 can be fit into 2080 2 times, resulting in a remainder of 640.
The next digit of our result is 2. 
Result so far: 12696.2
The remainder is 640 after subtracting 1440 from 2080.
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 9:
If we divide 6400 by 720, we get 8 and a remainder of 640.
Put 8 as the next digit of the answer. 
Result so far: 12696.28
Subtracting 5760 from 6400 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 10:
720 can be fit into 6400 8 times, resulting in a remainder of 640.
Record the quotient 8 as the next digit in the result. 
Result so far: 12696.288
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.

The final outcome is 12696.288, with a leftover of 0.064.
