We're dividing 616404 by 31 
We want to figure out the number of times 616404 can be divided by 31.

Step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 31

Going ahead to step 2:
31 goes into 61 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 31 from 61, we get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 31

Step 3:
If we divide 306 by 31, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 279 away from 306, we end up with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 31

Step 4:
The number 31 fits into 274 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 198.0
The remainder is 26 after subtracting 248 from 274.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 31

Let's proceed to step 5:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1988.0
If we subtract 248 from 260, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 31

Advancing to step 6:
If we divide 124 by 31, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 19884.0
If we subtract 124 from 124, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 31, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19884.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
31 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19884.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 19884.0 and a remainder of 0.0.
