We look at the division of 212360 by 31 
We want to figure out the number of times 212360 can be divided by 31.

Step 1:
31 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 31

Going ahead to step 2:
When dividing 21 by 31, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 31

Advancing to step 3:
When dividing 212 by 31, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 186 from 212 leaves us with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 31

On to step 4:
The number 31 fits into 263 8 times, leaving a remainder of 15.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 248 from 263 and we're left with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 31

On to step 5:
The number 31 fits into 156 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 685.0
Subtract 155 from 156 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 31

Let's proceed to step 6:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6850.0
Subtracting 0 from 10 leaves us 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.

Going ahead to step 7:
100 divided by 31 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 6850.3
Subtract 93 from 100 to 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:
31 goes into 70 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 6850.32
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.

Moving on to step 9:
When dividing 80 by 31, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 6850.322
If we take 62 away from 80, we end up 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.

The final result is 6850.322 with a remainder of 0.0018.
