We look at the division of 288699 by 90 
Our goal is to divide 288699 by 90.

On to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 90

Moving on to step 2:
28 divided by 90 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 90

On to step 3:
90 goes into 288 3 times with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 270 from 288 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 90

Let's proceed to step 4:
90 goes into 186 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we subtract 180 from 186, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 90

Advancing to step 5:
90 can be fit into 69 0 times, resulting in a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 320.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 90

Going ahead to step 6:
When dividing 699 by 90, we get 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 3207.0
Subtracting 630 from 699 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
The number 90 fits into 690 7 times, leaving a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 3207.7
If we subtract 630 from 690, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
90 goes into 600 6 times with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 3207.76
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
90 goes into 600 6 times with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 3207.766
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 3207.766 and a remainder of 0.006.
