We're dividing 453988 by 31 
Our goal is to divide 453988 by 31.

Going ahead to step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 31

On to step 2:
31 can be fit into 45 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 14 after subtracting 31 from 45.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 31

Let's proceed to step 3:
If we divide 143 by 31, we get 4 and a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 19 after subtracting 124 from 143.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 31

Let's proceed to step 4:
31 can be fit into 199 6 times, resulting in a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Deduct 186 from 199 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 31

On to step 5:
31 can be fit into 138 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 1464.0
Subtract 124 from 138 to get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 31

Advancing to step 6:
If we divide 148 by 31, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 14644.0
Deduct 124 from 148 and we're left 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.

On to step 7:
240 divided by 31 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 14644.7
If we subtract 217 from 240, we get 23.
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 8:
If we divide 230 by 31, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 14644.77
Subtracting 217 from 230 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 14644.77, with a leftover of 0.013.
