We divide 247439 by 90
We want to figure out the number of times 247439 can be divided by 90.

On to step 1:
90 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 90

Step 2:
90 can be fit into 24 0 times, resulting in a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 90

Going ahead to step 3:
90 goes into 247 2 times with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 180 from 247 and we're left with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 90

Going ahead to step 4:
674 divided by 90 is 7 with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 630 away from 674, we end up with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 90

Moving on to step 5:
90 can be fit into 443 4 times, resulting in a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 274.0
The remainder is 83 after subtracting 360 from 443.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 90

On to step 6:
90 can be fit into 839 9 times, resulting in a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 2749.0
The remainder is 29 after subtracting 810 from 839.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
When dividing 290 by 90, we get 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 2749.3
The remainder is 20 after subtracting 270 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 90 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2749.32
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 90, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2749.322
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 2749.322, with a leftover of 0.002.
