We divide 661880 by 36
We want to divide 661880 by 36.

On to step 1:
6 divided by 36 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 36

On to step 2:
The number 36 fits into 66 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 36 from 66 leaves us with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 36

Going ahead to step 3:
The number 36 fits into 301 8 times, leaving a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 288 from 301 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 36

Advancing to step 4:
When dividing 138 by 36, we get 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 183.0
If we take 108 away from 138, we end up with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 36

Moving on to step 5:
When dividing 308 by 36, we get 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 1838.0
The remainder is 20 after subtracting 288 from 308.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 36

Going ahead to step 6:
The number 36 fits into 200 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 18385.0
If we take 180 away from 200, we end up 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.

Going ahead to step 7:
When dividing 200 by 36, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 18385.5
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 36, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 18385.55
If we subtract 180 from 200, we get 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 result is 18385.55 with a remainder of 0.02.
