We're dividing 212808 by 90 
Our goal is to divide 212808 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
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 90

Let's proceed to step 2:
21 divided by 90 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 90

Going ahead to step 3:
If we divide 212 by 90, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 180 from 212 and we're left with 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 90

Let's proceed to step 4:
If we divide 328 by 90, we get 3 and a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 270 from 328 leaves us with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 90

Advancing to step 5:
If we divide 580 by 90, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 236.0
If we take 540 away from 580, we end up with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 90

Advancing to step 6:
408 divided by 90 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 2364.0
Subtract 360 from 408 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
90 can be fit into 480 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2364.5
The remainder is 30 after subtracting 450 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 2364.53
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 2364.533
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 2364.533 with a remaining 0.003.
