2258908 ÷ 90 
Our goal is to divide 2258908 by 90.

Advancing 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
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 90

Going ahead to step 2:
90 goes into 22 0 times with a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 90

Going ahead to step 3:
When dividing 225 by 90, we get 2 with a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 180 from 225 and we're left with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 90

Moving on to step 4:
458 divided by 90 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 450 from 458, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 90

Let's proceed to step 5:
The number 90 fits into 89 0 times, leaving a remainder of 89.
The next digit of our result is 0. 
Result so far: 250.0
Deduct 0 from 89 and we're left with 89.
Include the next digit (0) from the dividend after 89, then repeat: 890 / 90

Advancing to step 6:
90 goes into 890 9 times with a remainder of 80.
Record the quotient 9 as the next digit in the result. 
Result so far: 2509.0
If we subtract 810 from 890, we get 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 90

Going ahead to step 7:
The number 90 fits into 808 8 times, leaving a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 25098.0
If we subtract 720 from 808, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 8:
The number 90 fits into 880 9 times, leaving a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 25098.9
Subtracting 810 from 880 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
If we divide 700 by 90, we get 7 and a remainder of 70.
The next digit of our result is 7. 
Result so far: 25098.97
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
When dividing 700 by 90, we get 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 25098.977
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 25098.977 with a remaining 0.007.
