We look at the division of 610307 by 31 
We want to divide 610307 by 31.

Step 1:
The number 31 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 31

On to step 2:
When dividing 61 by 31, we get 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 31 from 61 and we're left with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 31

Moving on to step 3:
If we divide 300 by 31, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 279 away from 300, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 31

Going ahead to step 4:
The number 31 fits into 213 6 times, leaving a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 196.0
If we take 186 away from 213, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 31

Let's proceed to step 5:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 1968.0
Deduct 248 from 270 and we're left with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 31

Step 6:
227 divided by 31 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 19687.0
If we take 217 away from 227, 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.

On to step 7:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 19687.3
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
When dividing 70 by 31, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 19687.32
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 31, we get 2 and a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 19687.322
The remainder is 18 after subtracting 62 from 80.
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 outcome is 19687.322, with a leftover of 0.0018.
