Let's divide 405427 by 31
We want to figure out the number of times 405427 can be divided by 31.

Step 1:
31 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 31

Going ahead to step 2:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 31 away from 40, we end up with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 31

Going ahead to step 3:
The number 31 fits into 95 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 93 from 95 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 31

Let's proceed to step 4:
If we divide 24 by 31, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtracting 0 from 24 leaves us with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 31

Step 5:
When dividing 242 by 31, we get 7 with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 1307.0
Subtracting 217 from 242 leaves us with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 31

Step 6:
The number 31 fits into 257 8 times, leaving a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 13078.0
If we take 248 away from 257, 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.

Let's proceed to step 7:
31 goes into 90 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 13078.2
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.

Advancing to step 8:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 13078.29
Subtracting 279 from 280 leaves us 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 9:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13078.29
If we subtract 0 from 10, 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.

Advancing to step 10:
100 divided by 31 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 13078.2903
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.

Moving on to step 11:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 13078.29032
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 12:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 13078.290322
The remainder is 18 after subtracting 62 from 80.
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 13078.290322, and the remainder is 1.8e-06.
