We look at the division of 603856 by 31 
We want to figure out the number of times 603856 can be divided by 31.

On to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 31

Moving on to step 2:
31 can be fit into 60 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 31 from 60 leaves us with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 31

Going ahead to step 3:
293 divided by 31 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 279 from 293, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 31

Let's proceed to step 4:
31 can be fit into 148 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 194.0
The remainder is 24 after subtracting 124 from 148.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 31

Moving on to step 5:
245 divided by 31 is 7 with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 1947.0
If we subtract 217 from 245, we get 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 31

Let's proceed to step 6:
31 can be fit into 286 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 19479.0
The remainder is 7 after subtracting 279 from 286.
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 7:
31 goes into 70 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 19479.2
Subtract 62 from 70 to 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.

Going ahead to step 8:
If we divide 80 by 31, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 19479.22
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 quotient of the division is 19479.22, and the remainder is 0.018.
