We look at the division of 45168 by 31 
We want to figure out the number of times 45168 can be divided by 31.

Moving on to step 1:
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: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 31

Advancing to step 2:
45 divided by 31 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we take 31 away from 45, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 31

Let's proceed to step 3:
31 can be fit into 141 4 times, resulting in a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 124 away from 141, we end up with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 31

Going ahead to step 4:
176 divided by 31 is 5 with a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Subtracting 155 from 176 leaves us with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 31

Advancing to step 5:
The number 31 fits into 218 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 1457.0
If we take 217 away from 218, we end up 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.

Advancing to step 6:
If we divide 10 by 31, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1457.0
Subtracting 0 from 10 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:
If we divide 100 by 31, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 1457.03
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 31 fits into 70 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 1457.032
If we subtract 62 from 70, we 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.

Going ahead to step 9:
31 goes into 80 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1457.0322
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 final result is 1457.0322 with a remainder of 0.00018.
