We divide 666690 by 36
We're looking to find how many times 36 goes into 666690.

On to step 1:
36 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 36

Moving on to step 2:
66 divided by 36 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 36 from 66 to get 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 36

Let's proceed to step 3:
36 can be fit into 306 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 288 from 306 to get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 36

Let's proceed to step 4:
The number 36 fits into 186 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
If we take 180 away from 186, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 36

Moving on to step 5:
When dividing 69 by 36, we get 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1851.0
Deduct 36 from 69 and we're left with 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 36

Moving on to step 6:
330 divided by 36 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 18519.0
Subtracting 324 from 330 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 36, we get 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 18519.1
Subtract 36 from 60 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
When dividing 240 by 36, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 18519.16
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
240 divided by 36 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 18519.166
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 18519.166, with a leftover of 0.0024.
