We're dividing 290063 by 90 
Our goal is to divide 290063 by 90.

On to step 1:
2 divided by 90 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 90

Going ahead to step 2:
90 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 90

On to step 3:
90 goes into 290 3 times with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 270 from 290 leaves us with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 90

On to step 4:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 180 away from 200, we end up with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 90

On to step 5:
90 goes into 206 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 322.0
Subtracting 180 from 206 leaves us with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 90

On to step 6:
The number 90 fits into 263 2 times, leaving a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 3222.0
Deduct 180 from 263 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 7:
90 can be fit into 830 9 times, resulting in a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 3222.9
If we take 810 away from 830, we end up 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.

On to step 8:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 3222.92
Subtract 180 from 200 to 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.

On to step 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 3222.922
Subtracting 180 from 200 leaves us 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.

The final outcome is 3222.922, with a leftover of 0.002.
