We're dividing 258687 by 90 
Let's see how many times 90 fits into 258687.

Step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 90

Moving on to step 2:
90 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 90

Step 3:
If we divide 258 by 90, we get 2 and a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 180 from 258 leaves us with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 90

Let's proceed to step 4:
The number 90 fits into 786 8 times, leaving a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 720 from 786 and we're left with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 90

Step 5:
90 can be fit into 668 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 287.0
Subtract 630 from 668 to get 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 90

Advancing to step 6:
90 can be fit into 387 4 times, resulting in a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 2874.0
If we subtract 360 from 387, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
If we divide 270 by 90, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2874.3
Deduct 270 from 270 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2874.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
If we divide 0 by 90, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2874.3
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 2874.3 with a remaining 0.0.
