381992 divided by 31 
We're looking to find how many times 31 goes into 381992.

Going ahead to step 1:
3 divided by 31 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 31

Going ahead to step 2:
When dividing 38 by 31, we get 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.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 31

Going ahead to step 3:
The number 31 fits into 71 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 9 after subtracting 62 from 71.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 31

Let's proceed to step 4:
99 divided by 31 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we subtract 93 from 99, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 31

Let's proceed to step 5:
The number 31 fits into 69 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 1232.0
The remainder is 7 after subtracting 62 from 69.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 31

Moving on to step 6:
31 goes into 72 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 12322.0
If we subtract 62 from 72, 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.

Let's proceed to step 7:
When dividing 100 by 31, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 12322.3
Subtracting 93 from 100 leaves us 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 8:
If we divide 70 by 31, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12322.32
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.

On to step 9:
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: 12322.322
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.

The final outcome is 12322.322, with a leftover of 0.0018.
