We divide 3497121 by 990
Let's see how many times 990 fits into 3497121.

Step 1:
3 divided by 990 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 990

Moving on to step 2:
If we divide 34 by 990, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 990

Advancing to step 3:
If we divide 349 by 990, we get 0 and a remainder of 349.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 349 and we're left with 349.
Grab the next digit (7) from the dividend, add it to 349, then carry on: 3497 / 990

Let's proceed to step 4:
The number 990 fits into 3497 3 times, leaving a remainder of 527.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2970 from 3497 to get 527.
Bring next digit (1) of the dividend behind the 527 and repeat the process: 5271 / 990

Going ahead to step 5:
When dividing 5271 by 990, we get 5 with a remainder of 321.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 4950 from 5271 and we're left with 321.
Append the next digit (2) from the dividend to 321 and continue with: 3212 / 990

Step 6:
990 goes into 3212 3 times with a remainder of 242.
The next digit of our result is 3. 
Result so far: 353.0
If we subtract 2970 from 3212, we get 242.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 990

Step 7:
When dividing 2421 by 990, we get 2 with a remainder of 441.
Record the quotient 2 as the next digit in the result. 
Result so far: 3532.0
Deduct 1980 from 2421 and we're left with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Advancing to step 8:
The number 990 fits into 4410 4 times, leaving a remainder of 450.
Write down 4 as next digit of the result. 
Result so far: 3532.4
Deduct 3960 from 4410 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 9:
990 can be fit into 4500 4 times, resulting in a remainder of 540.
Use 4 as the next digit of our solution. 
Result so far: 3532.44
Deduct 3960 from 4500 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final outcome is 3532.44, with a leftover of 0.54.
