We look at the division of 455418 by 31 
We want to figure out the number of times 455418 can be divided by 31.

Advancing 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
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 31

Let's proceed to step 2:
31 can be fit into 45 1 times, resulting in 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 (5) from the dividend to 14 and continue with: 145 / 31

Moving on to step 3:
31 goes into 145 4 times with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 124 from 145, we get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 31

Let's proceed to step 4:
If we divide 214 by 31, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 146.0
If we take 186 away from 214, we end up with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 31

Advancing to step 5:
31 can be fit into 281 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1469.0
If we take 279 away from 281, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 31

Let's proceed to step 6:
28 divided by 31 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 14690.0
Subtract 0 from 28 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 7:
When dividing 280 by 31, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 14690.9
If we subtract 279 from 280, we get 1.
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 8:
10 divided by 31 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14690.9
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.

On to step 9:
The number 31 fits into 100 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 14690.903
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.

On to step 10:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 14690.9032
If we take 62 away from 70, we end up 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.

Moving on to step 11:
80 divided by 31 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 14690.90322
Deduct 62 from 80 and we're left 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.

After the division, we end up with 14690.90322 and a remainder of 1.8e-05.
