We're dividing 907972 by 1 
We're looking to find how many times 1 goes into 907972.

On to step 1:
9 divided by 1 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 9 from 9 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Advancing to step 2:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

On to step 3:
1 goes into 7 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 907.0
If we take 7 away from 7, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

On to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 9079.0
If we take 9 away from 9, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Going ahead to step 5:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 90797.0
Subtract 7 from 7 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Step 6:
When dividing 2 by 1, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 907972.0
Subtracting 2 from 2 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.

Step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 907972.0
If we take 0 away from 0, 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.

Let's proceed to step 8:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 907972.0
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 907972.0, with a leftover of 0.0.
