We look at the division of 2257489 by 90 
We want to figure out the number of times 2257489 can be divided by 90.

On to step 1:
90 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 90

Moving on to step 2:
90 can be fit into 22 0 times, resulting in a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 90

Let's proceed to step 3:
When dividing 225 by 90, we get 2 with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 180 from 225 and we're left with 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 90

On to step 4:
The number 90 fits into 457 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 450 from 457 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 90

On to step 5:
When dividing 74 by 90, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 250.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 90

On to step 6:
90 goes into 748 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 2508.0
If we take 720 away from 748, we end up with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 90

Going ahead to step 7:
The number 90 fits into 289 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 25083.0
Deduct 270 from 289 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
If we divide 190 by 90, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 25083.2
Subtract 180 from 190 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 90 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 25083.21
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
90 can be fit into 100 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 25083.211
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 25083.211 with a balance of 0.001.
