We look at the division of 97290073 by 9 
We want to divide 97290073 by 9.

Step 1:
9 divided by 9 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 9

Going ahead to step 2:
If we divide 7 by 9, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 9

Step 3:
If we divide 72 by 9, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 72 from 72, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 9

Going ahead to step 4:
The number 9 fits into 9 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1081.0
Subtract 9 from 9 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 9

Let's proceed to step 5:
9 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10810.0
If we subtract 0 from 0, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 9

Step 6:
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: 108100.0
Subtract 0 from 0 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 9

On to step 7:
7 divided by 9 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 1081000.0
If we subtract 0 from 7, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 9

Advancing to step 8:
When dividing 73 by 9, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 10810008.0
If we subtract 72 from 73, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
The number 9 fits into 10 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 10810008.1
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 9, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 10810008.11
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 10810008.11 with a remainder of 0.001.
