We divide 439103 by 31
Our goal is to divide 439103 by 31.

Going ahead to step 1:
If we divide 4 by 31, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 31

Moving on to step 2:
43 divided by 31 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 31 from 43 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 31

Going ahead to step 3:
The number 31 fits into 129 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 124 from 129 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 31

Going ahead to step 4:
If we divide 51 by 31, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Subtracting 31 from 51 leaves us with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 31

Moving on to step 5:
31 goes into 200 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 1416.0
If we take 186 away from 200, we end up with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 31

On to step 6:
When dividing 143 by 31, we get 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 14164.0
Subtract 124 from 143 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
190 divided by 31 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 14164.6
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 31, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 14164.61
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
90 divided by 31 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 14164.612
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
If we divide 280 by 31, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 14164.6129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 14164.6129
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
31 goes into 100 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 14164.612903
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.

Let's proceed to step 13:
If we divide 70 by 31, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 14164.6129032
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.

Step 14:
When dividing 80 by 31, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 14164.61290322
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 final outcome is 14164.61290322, with a leftover of 1.8e-08.
