We're dividing 7185 by 31 
We're looking to find how many times 31 goes into 7185.

On to step 1:
When dividing 7 by 31, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 31

Let's proceed to step 2:
If we divide 71 by 31, we get 2 and a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 62 from 71, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 31

Let's proceed to step 3:
The number 31 fits into 98 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 93 from 98, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 31

Going ahead to step 4:
31 goes into 55 1 times with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 231.0
Deduct 31 from 55 and we're left 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.

Step 5:
240 divided by 31 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 231.7
Subtract 217 from 240 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 6:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 231.77
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 231.77 with a balance of 0.013.
