297939 ÷ 90 
We want to figure out the number of times 297939 can be divided by 90.

Going ahead to step 1:
90 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 90

On to step 2:
90 goes into 29 0 times with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 90

Going ahead to step 3:
If we divide 297 by 90, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 270 away from 297, we end up with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 90

Let's proceed to step 4:
When dividing 279 by 90, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 270 from 279, we get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 90

Going ahead to step 5:
If we divide 93 by 90, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 331.0
Deduct 90 from 93 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 90

On to step 6:
90 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 3310.0
If we take 0 away from 39, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
If we divide 390 by 90, we get 4 and a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 3310.4
Subtracting 360 from 390 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 3310.43
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
When dividing 300 by 90, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 3310.433
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 3310.433, with a leftover of 0.003.
