We look at the division of 66391281 by 360 
We want to figure out the number of times 66391281 can be divided by 360.

Let's proceed to step 1:
360 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 360

Advancing to step 2:
When dividing 66 by 360, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 360

On to step 3:
The number 360 fits into 663 1 times, leaving a remainder of 303.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 360 from 663, we get 303.
Bring next digit (9) of the dividend behind the 303 and repeat the process: 3039 / 360

On to step 4:
360 can be fit into 3039 8 times, resulting in a remainder of 159.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 2880 from 3039 leaves us with 159.
Append the next digit (1) from the dividend to 159 and continue with: 1591 / 360

Going ahead to step 5:
1591 divided by 360 is 4 with a remainder of 151.
The next digit of our result is 4. 
Result so far: 184.0
Deduct 1440 from 1591 and we're left with 151.
Take the next digit (2) from the dividend and append it to 151, then repeat: 1512 / 360

Step 6:
If we divide 1512 by 360, we get 4 and a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1844.0
If we subtract 1440 from 1512, we get 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 360

Step 7:
728 divided by 360 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 18442.0
Subtracting 720 from 728 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 360

Moving on to step 8:
When dividing 81 by 360, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 184420.0
Deduct 0 from 81 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
360 goes into 810 2 times with a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 184420.2
Subtracting 720 from 810 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
900 divided by 360 is 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 184420.22
Deduct 720 from 900 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 184420.22 with a remaining 0.18.
