28401457 ÷ 90 
Our goal is to divide 28401457 by 90.

Advancing to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 90

Advancing to step 2:
28 divided by 90 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 90

Moving on to step 3:
If we divide 284 by 90, we get 3 and a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 270 away from 284, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 90

On to step 4:
90 can be fit into 140 1 times, resulting in a remainder of 50.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 90 from 140, we get 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 90

On to step 5:
If we divide 501 by 90, we get 5 and a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 315.0
If we take 450 away from 501, we end up with 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 90

Advancing to step 6:
90 can be fit into 514 5 times, resulting in a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 3155.0
If we take 450 away from 514, we end up with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 90

Going ahead to step 7:
The number 90 fits into 645 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 31557.0
Subtracting 630 from 645 leaves us with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 90

Moving on to step 8:
157 divided by 90 is 1 with a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 315571.0
If we subtract 90 from 157, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
90 goes into 670 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 315571.7
If we take 630 away from 670, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 315571.74
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 315571.744
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 315571.744 with a remaining 0.004.
