We look at the division of 209857 by 85 
We want to figure out the number of times 209857 can be divided by 85.

Let's proceed to step 1:
85 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
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 85

Let's proceed to step 2:
85 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 85

Moving on to step 3:
85 goes into 209 2 times with a remainder of 39.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 170 from 209 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 85

Moving on to step 4:
The number 85 fits into 398 4 times, leaving a remainder of 58.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 58 after subtracting 340 from 398.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 85

Moving on to step 5:
The number 85 fits into 585 6 times, leaving a remainder of 75.
The next digit of our result is 6. 
Result so far: 246.0
If we take 510 away from 585, we end up with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 85

Step 6:
757 divided by 85 is 8 with a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 2468.0
Subtract 680 from 757 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
If we divide 770 by 85, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 2468.9
The remainder is 5 after subtracting 765 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
50 divided by 85 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 2468.9
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 85 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 2468.905
The remainder is 75 after subtracting 425 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The next digit of our result is 8. 
Result so far: 2468.9058
If we take 680 away from 750, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 2468.90588
Deduct 680 from 700 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 2468.90588, with a leftover of 2e-05.
