385805 divided by 31 
We want to divide 385805 by 31.

Let's proceed to step 1:
If we divide 3 by 31, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 31

On to step 2:
When dividing 38 by 31, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 31 from 38 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 31

Let's proceed to step 3:
The number 31 fits into 75 2 times, leaving a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 62 from 75, we get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 31

Advancing to step 4:
31 goes into 138 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 124.0
If we take 124 away from 138, we end up with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 31

Going ahead to step 5:
If we divide 140 by 31, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 1244.0
If we subtract 124 from 140, we get 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 31

Moving on to step 6:
If we divide 165 by 31, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 12445.0
If we take 155 away from 165, we end up 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 7:
31 goes into 100 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 12445.3
If we subtract 93 from 100, we 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.

Moving on to step 8:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12445.32
The remainder is 8 after subtracting 62 from 70.
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:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12445.322
If we subtract 62 from 80, we 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.

The quotient of the division is 12445.322, and the remainder is 0.0018.
