We look at the division of 45243301 by 317 
We want to figure out the number of times 45243301 can be divided by 317.

Step 1:
4 divided by 317 is 0 with 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.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 317

Going ahead to step 2:
If we divide 45 by 317, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 317

On to step 3:
If we divide 452 by 317, we get 1 and a remainder of 135.
The next digit of our result is 1. 
Result so far: 1.0
If we take 317 away from 452, we end up with 135.
Bring next digit (4) of the dividend behind the 135 and repeat the process: 1354 / 317

Let's proceed to step 4:
When dividing 1354 by 317, we get 4 with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 1268 from 1354 to get 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 317

Going ahead to step 5:
The number 317 fits into 863 2 times, leaving a remainder of 229.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
If we take 634 away from 863, we end up with 229.
Append the next digit (3) from the dividend to 229 and continue with: 2293 / 317

On to step 6:
The number 317 fits into 2293 7 times, leaving a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 1427.0
If we subtract 2219 from 2293, we get 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 317

Let's proceed to step 7:
When dividing 740 by 317, we get 2 with a remainder of 106.
Use 2 as the next digit of our solution. 
Result so far: 14272.0
The remainder is 106 after subtracting 634 from 740.
Include the next digit (1) from the dividend after 106, then repeat: 1061 / 317

Going ahead to step 8:
If we divide 1061 by 317, we get 3 and a remainder of 110.
Use 3 as the next digit of our solution. 
Result so far: 142723.0
Deduct 951 from 1061 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 9:
The number 317 fits into 1100 3 times, leaving a remainder of 149.
Record the quotient 3 as the next digit in the result. 
Result so far: 142723.3
Deduct 951 from 1100 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 10:
If we divide 1490 by 317, we get 4 and a remainder of 222.
The next digit of our result is 4. 
Result so far: 142723.34
If we subtract 1268 from 1490, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 11:
2220 divided by 317 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 142723.347
Deduct 2219 from 2220 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.

Let's proceed to step 12:
The number 317 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 142723.347
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.

Step 13:
317 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 142723.347
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 142723.347 with a remainder of 0.0001.
