We're dividing 209746 by 512 
We want to divide 209746 by 512.

Let's proceed to step 1:
512 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 512

Moving on to step 2:
If we divide 20 by 512, we get 0 and 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.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 512

On to step 3:
If we divide 209 by 512, we get 0 and a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Include the next digit (7) from the dividend after 209, then repeat: 2097 / 512

Let's proceed to step 4:
512 can be fit into 2097 4 times, resulting in a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2048 from 2097 and we're left with 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 512

Advancing to step 5:
When dividing 494 by 512, we get 0 with a remainder of 494.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 494 after subtracting 0 from 494.
Grab the next digit (6) from the dividend, add it to 494, then carry on: 4946 / 512

On to step 6:
When dividing 4946 by 512, we get 9 with a remainder of 338.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
Deduct 4608 from 4946 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 7:
The number 512 fits into 3380 6 times, leaving a remainder of 308.
Write down 6 as next digit of the result. 
Result so far: 409.6
If we subtract 3072 from 3380, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 8:
3080 divided by 512 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 409.66
The remainder is 8 after subtracting 3072 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 409.66 with a remainder of 0.008.
