We look at the division of 430671 by 31 
We're looking to find how many times 31 goes into 430671.

Moving on to step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 31

Let's proceed to step 2:
31 can be fit into 43 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 31 from 43 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 31

Moving on to step 3:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 93 from 120 leaves us with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 31

Advancing to step 4:
The number 31 fits into 276 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 138.0
The remainder is 28 after subtracting 248 from 276.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 31

Advancing to step 5:
The number 31 fits into 287 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 1389.0
The remainder is 8 after subtracting 279 from 287.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 31

Going ahead to step 6:
31 goes into 81 2 times with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 13892.0
Deduct 62 from 81 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
If we divide 190 by 31, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 13892.6
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
The number 31 fits into 40 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 13892.61
Subtracting 31 from 40 leaves us with 9.
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:
If we divide 90 by 31, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 13892.612
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.

Let's proceed to step 10:
280 divided by 31 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 13892.6129
Subtracting 279 from 280 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to 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: 13892.6129
Deduct 0 from 10 and we're left 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.

Moving on to step 12:
The number 31 fits into 100 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 13892.612903
Subtract 93 from 100 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.

Advancing to step 13:
31 goes into 70 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 13892.6129032
Deduct 62 from 70 and we're left 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.

Let's proceed to step 14:
31 goes into 80 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 13892.61290322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 13892.61290322 with a remaining 1.8e-08.
