We divide 431446 by 31
Our goal is to divide 431446 by 31.

Step 1:
4 divided by 31 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 31

On to step 2:
31 goes into 43 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 31 from 43 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 31

Going ahead to step 3:
121 divided by 31 is 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 93 from 121 to get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 31

On to step 4:
If we divide 284 by 31, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 139.0
If we subtract 279 from 284, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 31

Advancing to step 5:
31 goes into 54 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1391.0
The remainder is 23 after subtracting 31 from 54.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 31

Moving on to step 6:
31 goes into 236 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 13917.0
The remainder is 19 after subtracting 217 from 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
31 can be fit into 190 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 13917.6
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.

Going ahead to step 8:
If we divide 40 by 31, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 13917.61
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
The number 31 fits into 90 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 13917.612
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
When dividing 280 by 31, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 13917.6129
Deduct 279 from 280 and we're left 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.

Let's proceed to step 11:
If we divide 10 by 31, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13917.6129
Subtract 0 from 10 to 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.

On to step 12:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 13917.612903
If we take 93 away from 100, we end up 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.

Step 13:
70 divided by 31 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 13917.6129032
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.

On to step 14:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 13917.61290322
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.

After the division, we end up with 13917.61290322 and a remainder of 1.8e-08.
