Let's divide 243247 by 90
Our goal is to divide 243247 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
Subtract 0 from 2 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 90

Step 2:
24 divided by 90 is 0 with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 90

On to step 3:
90 goes into 243 2 times with a remainder of 63.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 180 away from 243, we end up with 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 90

Advancing to step 4:
If we divide 632 by 90, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we subtract 630 from 632, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 90

Going ahead to step 5:
When dividing 24 by 90, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 270.0
Subtract 0 from 24 to get 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 90

Moving on to step 6:
247 divided by 90 is 2 with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 2702.0
Subtracting 180 from 247 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
670 divided by 90 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 2702.7
Subtract 630 from 670 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
90 goes into 400 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 2702.74
Subtracting 360 from 400 leaves us 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.

On to step 9:
90 goes into 400 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 2702.744
Subtracting 360 from 400 leaves us 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.

Our division results in 2702.744 with a remaining 0.004.
