We divide 210050 by 90
Let's see how many times 90 fits into 210050.

On to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 90

Moving on to step 2:
If we divide 21 by 90, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 90

Let's proceed to step 3:
When dividing 210 by 90, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 30 after subtracting 180 from 210.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 90

On to step 4:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 270 from 300, we get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 90

Step 5:
If we divide 305 by 90, we get 3 and a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
Deduct 270 from 305 and we're left with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 90

Let's proceed to step 6:
The number 90 fits into 350 3 times, leaving a remainder of 80.
The next digit of our result is 3. 
Result so far: 2333.0
Deduct 270 from 350 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 7:
90 goes into 800 8 times with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 2333.8
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
90 goes into 800 8 times with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 2333.88
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 2333.88 and a remainder of 0.08.
