We look at the division of 30489141 by 997 
We want to divide 30489141 by 997.

Advancing to step 1:
When dividing 3 by 997, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 997

Moving on to step 2:
997 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 997

On to step 3:
When dividing 304 by 997, we get 0 with a remainder of 304.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 304 and we're left with 304.
Include the next digit (8) from the dividend after 304, then repeat: 3048 / 997

Moving on to step 4:
The number 997 fits into 3048 3 times, leaving a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 2991 from 3048, we get 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 997

Going ahead to step 5:
The number 997 fits into 579 0 times, leaving a remainder of 579.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 579 and we're left with 579.
Grab the next digit (1) from the dividend, add it to 579, then carry on: 5791 / 997

Step 6:
997 goes into 5791 5 times with a remainder of 806.
Record the quotient 5 as the next digit in the result. 
Result so far: 305.0
Deduct 4985 from 5791 and we're left with 806.
Include the next digit (4) from the dividend after 806, then repeat: 8064 / 997

Advancing to step 7:
997 can be fit into 8064 8 times, resulting in a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 3058.0
Deduct 7976 from 8064 and we're left with 88.
Append the next digit (1) from the dividend to 88 and continue with: 881 / 997

Advancing to step 8:
997 goes into 881 0 times with a remainder of 881.
Write down 0 as next digit of the result. 
Result so far: 30580.0
Subtract 0 from 881 to get 881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8810, and continue the process.

Let's proceed to step 9:
When dividing 8810 by 997, we get 8 with a remainder of 834.
The next digit of our result is 8. 
Result so far: 30580.8
Subtracting 7976 from 8810 leaves us with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Step 10:
8340 divided by 997 is 8 with a remainder of 364.
Put 8 as the next digit of the answer. 
Result so far: 30580.88
Deduct 7976 from 8340 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final outcome is 30580.88, with a leftover of 0.364.
