We look at the division of 49603231 by 31 
We're looking to find how many times 31 goes into 49603231.

On to step 1:
The number 31 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 31

Moving on to step 2:
When dividing 49 by 31, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 31 from 49 and we're left with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 31

On to step 3:
186 divided by 31 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 186 from 186 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 31

Advancing to step 4:
31 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Subtract 0 from 0 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 31

On to step 5:
The number 31 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 1600.0
If we take 0 away from 3, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 31

Let's proceed to step 6:
32 divided by 31 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 16001.0
Deduct 31 from 32 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 31

Step 7:
The number 31 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 160010.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 31

Let's proceed to step 8:
When dividing 131 by 31, we get 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 1600104.0
Subtract 124 from 131 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.

On to step 9:
31 goes into 70 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1600104.2
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 31 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1600104.22
Deduct 62 from 80 and we're left 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 1600104.22, and the remainder is 0.018.
