We're dividing 270397 by 90 
Our goal is to divide 270397 by 90.

Let's proceed to step 1:
90 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 90

Advancing to step 2:
If we divide 27 by 90, we get 0 and a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 90

On to step 3:
270 divided by 90 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 0 after subtracting 270 from 270.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 90

Going ahead to step 4:
90 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 90

Step 5:
When dividing 39 by 90, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 90

Moving on to step 6:
When dividing 397 by 90, we get 4 with a remainder of 37.
The next digit of our result is 4. 
Result so far: 3004.0
Subtracting 360 from 397 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
The number 90 fits into 370 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 3004.4
The remainder is 10 after subtracting 360 from 370.
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 8:
100 divided by 90 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 3004.41
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.

Step 9:
90 can be fit into 100 1 times, resulting in a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 3004.411
Subtracting 90 from 100 leaves us 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.

The quotient of the division is 3004.411, and the remainder is 0.001.
