403481 divided by 31 
We want to figure out the number of times 403481 can be divided by 31.

Step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 31

Let's proceed to step 2:
40 divided by 31 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 31 from 40 leaves us with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 31

Step 3:
The number 31 fits into 93 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 0 after subtracting 93 from 93.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 31

Going ahead to step 4:
If we divide 4 by 31, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 130.0
If we take 0 away from 4, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 31

Moving on to step 5:
48 divided by 31 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1301.0
If we take 31 away from 48, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 31

Advancing to step 6:
If we divide 171 by 31, we get 5 and a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 13015.0
If we subtract 155 from 171, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 31 fits into 160 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 13015.5
If we take 155 away from 160, we end up 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 8:
If we divide 50 by 31, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 13015.51
If we subtract 31 from 50, we 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.

On to step 9:
31 goes into 190 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 13015.516
Subtracting 186 from 190 leaves us 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.

On to step 10:
31 goes into 40 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 13015.5161
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.

Moving on to step 11:
31 goes into 90 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 13015.51612
The remainder is 28 after subtracting 62 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 12:
31 can be fit into 280 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 13015.516129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
If we divide 10 by 31, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 13015.516129
If we take 0 away from 10, 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.

Let's proceed to step 14:
When dividing 100 by 31, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 13015.51612903
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.

Our division results in 13015.51612903 with a remaining 7e-09.
