We look at the division of 23508860 by 459 
We want to figure out the number of times 23508860 can be divided by 459.

Going ahead to step 1:
459 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 459

Advancing to step 2:
23 divided by 459 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 459

Going ahead to step 3:
235 divided by 459 is 0 with a remainder of 235.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 235, we get 235.
Grab the next digit (0) from the dividend, add it to 235, then carry on: 2350 / 459

Step 4:
2350 divided by 459 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 2295 from 2350 leaves us with 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 459

On to step 5:
When dividing 558 by 459, we get 1 with a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtracting 459 from 558 leaves us with 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 459

Step 6:
The number 459 fits into 998 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 512.0
If we take 918 away from 998, we end up with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 459

Step 7:
The number 459 fits into 806 1 times, leaving a remainder of 347.
Put 1 as the next digit of the answer. 
Result so far: 5121.0
If we subtract 459 from 806, we get 347.
Take the next digit (0) from the dividend and append it to 347, then repeat: 3470 / 459

Moving on to step 8:
When dividing 3470 by 459, we get 7 with a remainder of 257.
Write down 7 as next digit of the result. 
Result so far: 51217.0
If we take 3213 away from 3470, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 9:
When dividing 2570 by 459, we get 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 51217.5
Subtracting 2295 from 2570 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 10:
459 goes into 2750 5 times with a remainder of 455.
Use 5 as the next digit of our solution. 
Result so far: 51217.55
Deduct 2295 from 2750 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

The final result is 51217.55 with a remainder of 0.455.
