We look at the division of 516191 by 31 
We want to figure out the number of times 516191 can be divided by 31.

Moving on to step 1:
5 divided by 31 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 31

On to step 2:
When dividing 51 by 31, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 20 after subtracting 31 from 51.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 31

On to step 3:
When dividing 206 by 31, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 186 away from 206, we end up with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 31

Moving on to step 4:
31 goes into 201 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 166.0
Deduct 186 from 201 and we're left with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 31

Let's proceed to step 5:
When dividing 159 by 31, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 1665.0
Subtract 155 from 159 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 31

Step 6:
When dividing 41 by 31, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 16651.0
If we take 31 away from 41, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
When dividing 100 by 31, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 16651.3
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
70 divided by 31 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 16651.32
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
80 divided by 31 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 16651.322
Subtracting 62 from 80 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 16651.322 and a remainder of 0.0018.
