We're dividing 383458 by 31 
We want to divide 383458 by 31.

Step 1:
31 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 31

Going ahead to step 2:
38 divided by 31 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 31 from 38 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 31

Moving on to step 3:
When dividing 73 by 31, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 62 away from 73, we end up with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 31

Step 4:
When dividing 114 by 31, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtracting 93 from 114 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 31

Let's proceed to step 5:
If we divide 215 by 31, we get 6 and a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 1236.0
If we take 186 away from 215, we end up with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 31

On to step 6:
If we divide 298 by 31, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 12369.0
The remainder is 19 after subtracting 279 from 298.
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:
190 divided by 31 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 12369.6
The remainder is 4 after subtracting 186 from 190.
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:
31 goes into 40 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 12369.61
If we take 31 away from 40, we end up 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.

On to step 9:
31 goes into 90 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 12369.612
Subtract 62 from 90 to 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.

Going ahead to step 10:
When dividing 280 by 31, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 12369.6129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
If we divide 10 by 31, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12369.6129
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:
100 divided by 31 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 12369.612903
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.

On to step 13:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12369.6129032
Subtracting 62 from 70 leaves us 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 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: 12369.61290322
Subtracting 62 from 80 leaves us 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 12369.61290322, and the remainder is 1.8e-08.
