Let's divide 90720 by 1
We want to figure out the number of times 90720 can be divided by 1.

Going ahead to step 1:
When dividing 9 by 1, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 9 from 9, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Advancing to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Let's proceed to step 3:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 907.0
Subtracting 7 from 7 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Advancing to step 4:
1 goes into 2 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 9072.0
If we take 2 away from 2, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Step 5:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90720.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90720.0
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.

Going ahead to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90720.0
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.

The final outcome is 90720.0, with a leftover of 0.0.
