Let's divide 239759 by 90
Our goal is to divide 239759 by 90.

Going ahead to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 90

Advancing to step 2:
23 divided by 90 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 90

Step 3:
90 goes into 239 2 times with a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 180 from 239 leaves us with 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 90

Going ahead to step 4:
90 can be fit into 597 6 times, resulting in a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 540 away from 597, we end up with 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 90

Step 5:
When dividing 575 by 90, we get 6 with a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 266.0
Subtract 540 from 575 to get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 90

Advancing to step 6:
The number 90 fits into 359 3 times, leaving a remainder of 89.
Use 3 as the next digit of our solution. 
Result so far: 2663.0
Deduct 270 from 359 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 7:
When dividing 890 by 90, we get 9 with a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 2663.9
Deduct 810 from 890 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
If we divide 800 by 90, we get 8 and a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 2663.98
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
If we divide 800 by 90, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 2663.988
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 2663.988, and the remainder is 0.008.
