Let's divide 405885 by 31
Let's see how many times 31 fits into 405885.

Let's proceed to step 1:
31 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 31

Going ahead to step 2:
31 goes into 40 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 31 from 40, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 31

On to step 3:
If we divide 95 by 31, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 93 from 95 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 31

Moving on to step 4:
28 divided by 31 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 130.0
If we take 0 away from 28, we end up with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 31

On to step 5:
288 divided by 31 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 1309.0
Subtracting 279 from 288 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 31

Moving on to step 6:
31 can be fit into 95 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 13093.0
The remainder is 2 after subtracting 93 from 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
31 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 13093.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 31, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 13093.06
Subtracting 186 from 200 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
31 goes into 140 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 13093.064
Deduct 124 from 140 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 31, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 13093.0645
Subtracting 155 from 160 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
If we divide 50 by 31, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 13093.06451
Subtract 31 from 50 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 13093.064516
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.

Step 13:
31 can be fit into 40 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 13093.0645161
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.

Going ahead to step 14:
31 can be fit into 90 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 13093.06451612
Deduct 62 from 90 and we're left 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.

Our division results in 13093.06451612 with a remaining 2.8e-08.
