We look at the division of 457008 by 87 
We're looking to find how many times 87 goes into 457008.

Let's proceed to step 1:
If we divide 4 by 87, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 87

Advancing to step 2:
The number 87 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 87

Going ahead to step 3:
If we divide 457 by 87, we get 5 and a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 435 from 457 and we're left with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 87

On to step 4:
The number 87 fits into 220 2 times, leaving a remainder of 46.
The next digit of our result is 2. 
Result so far: 52.0
Deduct 174 from 220 and we're left with 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 87

Going ahead to step 5:
The number 87 fits into 460 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 525.0
If we subtract 435 from 460, we get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 87

Going ahead to step 6:
87 goes into 258 2 times with a remainder of 84.
Use 2 as the next digit of our solution. 
Result so far: 5252.0
Deduct 174 from 258 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 7:
87 goes into 840 9 times with a remainder of 57.
The next digit of our result is 9. 
Result so far: 5252.9
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 8:
If we divide 570 by 87, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 5252.96
The remainder is 48 after subtracting 522 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
87 goes into 480 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5252.965
If we subtract 435 from 480, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
87 can be fit into 450 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5252.9655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 5252.9655 with a remaining 0.00015.
