450803 divided by 31 
We want to figure out the number of times 450803 can be divided by 31.

On to 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 subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 31

Moving on to step 2:
When dividing 45 by 31, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 31 from 45 to get 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 31

Step 3:
The number 31 fits into 140 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 124 from 140, we get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 31

Advancing to step 4:
31 goes into 168 5 times with a remainder of 13.
The next digit of our result is 5. 
Result so far: 145.0
If we take 155 away from 168, we end up with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 31

Moving on to step 5:
31 can be fit into 130 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1454.0
If we take 124 away from 130, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 31

Moving on to step 6:
31 goes into 63 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 14542.0
Deduct 62 from 63 and we're left 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.

On to step 7:
10 divided by 31 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 14542.0
Subtract 0 from 10 to 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 8:
100 divided by 31 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 14542.03
If we take 93 away from 100, we end up 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 9:
31 goes into 70 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 14542.032
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.

Step 10:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 14542.0322
If we take 62 away from 80, we end up 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 final result is 14542.0322 with a remainder of 0.00018.
