We look at the division of 205710 by 90 
We want to figure out the number of times 205710 can be divided by 90.

Let's proceed to step 1:
2 divided by 90 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 90

Let's proceed to step 2:
The number 90 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 90

Moving on to step 3:
90 goes into 205 2 times with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 180 from 205 and we're left with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 90

On to step 4:
If we divide 257 by 90, we get 2 and a remainder of 77.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 180 from 257 to get 77.
Fetch the next digit (1) from the dividend, attach it to 77 and continue: 771 / 90

Step 5:
90 goes into 771 8 times with a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 228.0
Subtract 720 from 771 to get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 90

Advancing to step 6:
When dividing 510 by 90, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 2285.0
If we take 450 away from 510, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
If we divide 600 by 90, we get 6 and a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 2285.6
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
600 divided by 90 is 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 2285.66
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 2285.66 and a remainder of 0.06.
