We divide 408530 by 31
We're looking to find how many times 31 goes into 408530.

Let's proceed to step 1:
The number 31 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 31

Let's proceed to step 2:
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: 1.0
If we subtract 31 from 40, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 31

Moving on to step 3:
31 goes into 98 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13.0
The remainder is 5 after subtracting 93 from 98.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 31

Going ahead to step 4:
55 divided by 31 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we subtract 31 from 55, we get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 31

Let's proceed to step 5:
If we divide 243 by 31, we get 7 and a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 1317.0
If we take 217 away from 243, we end up with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 31

Advancing to step 6:
When dividing 260 by 31, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 13178.0
If we subtract 248 from 260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
31 goes into 120 3 times with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 13178.3
The remainder is 27 after subtracting 93 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
The number 31 fits into 270 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 13178.38
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
31 goes into 220 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 13178.387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
If we divide 30 by 31, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 13178.387
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 31 fits into 300 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 13178.38709
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
210 divided by 31 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 13178.387096
Subtracting 186 from 210 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
240 divided by 31 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 13178.3870967
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
31 goes into 230 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 13178.38709677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 13178.38709677 with a remaining 1.3e-08.
