Let's divide 721779 by 10
Let's see how many times 10 fits into 721779.

Let's proceed to step 1:
The number 10 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 10

Advancing to step 2:
If we divide 72 by 10, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 70 from 72 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 10

Advancing to step 3:
21 divided by 10 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 1 after subtracting 20 from 21.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 10

Step 4:
17 divided by 10 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 721.0
If we subtract 10 from 17, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 10

Step 5:
10 can be fit into 77 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7217.0
Subtract 70 from 77 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 10

Moving on to step 6:
When dividing 79 by 10, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 72177.0
Subtracting 70 from 79 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 10 fits into 90 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 72177.9
Deduct 90 from 90 and we're left 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.

Step 8:
10 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 72177.9
Deduct 0 from 0 and we're left 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.

Going ahead to step 9:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 72177.9
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.

The final outcome is 72177.9, with a leftover of 0.0.
