Let's divide 721377 by 9
We want to figure out the number of times 721377 can be divided by 9.

Moving on to step 1:
When dividing 7 by 9, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 9

Step 2:
9 can be fit into 72 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 72 from 72 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 9

On to step 3:
When dividing 1 by 9, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 80.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 9

Going ahead to step 4:
13 divided by 9 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 801.0
Deduct 9 from 13 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 9

Advancing to step 5:
9 can be fit into 47 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 8015.0
The remainder is 2 after subtracting 45 from 47.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 9

Advancing to step 6:
When dividing 27 by 9, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 80153.0
If we take 27 away from 27, we end up 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 7:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80153.0
If we subtract 0 from 0, 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.

Advancing to step 8:
If we divide 0 by 9, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80153.0
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 80153.0, with a leftover of 0.0.
