We're dividing 665850 by 36 
We want to divide 665850 by 36.

On to step 1:
The number 36 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 36

Let's proceed to step 2:
36 can be fit into 66 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 36 away from 66, we end up with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 36

Advancing to step 3:
When dividing 305 by 36, we get 8 with a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 288 from 305 and we're left with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 36

Going ahead to step 4:
The number 36 fits into 178 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
Subtracting 144 from 178 leaves us with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 36

On to step 5:
36 can be fit into 345 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 1849.0
The remainder is 21 after subtracting 324 from 345.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 36

On to step 6:
When dividing 210 by 36, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 18495.0
The remainder is 30 after subtracting 180 from 210.
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 7:
The number 36 fits into 300 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 18495.8
Deduct 288 from 300 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 36, we get 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 18495.83
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
36 can be fit into 120 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 18495.833
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 18495.833, with a leftover of 0.0012.
