We divide 450936 by 31
Let's see how many times 31 fits into 450936.

Moving on to step 1:
31 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 31

Let's proceed to step 2:
When dividing 45 by 31, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 31 from 45 and we're left with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 31

Step 3:
140 divided by 31 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 124 from 140, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 31

Going ahead to step 4:
When dividing 169 by 31, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 145.0
Subtracting 155 from 169 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 31

Let's proceed to step 5:
If we divide 143 by 31, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 1454.0
Subtracting 124 from 143 leaves us with 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 31

Advancing to step 6:
When dividing 196 by 31, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 14546.0
Subtracting 186 from 196 leaves us 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.

Advancing to step 7:
When dividing 100 by 31, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 14546.3
Deduct 93 from 100 and we're left 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.

On to step 8:
70 divided by 31 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 14546.32
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 31, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 14546.322
Subtracting 62 from 80 leaves us with 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 14546.322, and the remainder is 0.0018.
