We're dividing 458487 by 8 
Let's see how many times 8 fits into 458487.

Let's proceed to step 1:
4 divided by 8 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 8

On to step 2:
When dividing 45 by 8, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 40 from 45 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 8

Step 3:
8 can be fit into 58 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 57.0
Subtracting 56 from 58 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 8

Advancing to step 4:
8 goes into 24 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 573.0
If we subtract 24 from 24, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 8

Moving on to step 5:
8 can be fit into 8 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 5731.0
If we subtract 8 from 8, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 8

Advancing to step 6:
8 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 57310.0
Subtract 0 from 7 to 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.

Advancing to step 7:
8 goes into 70 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 57310.8
Subtracting 64 from 70 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
When dividing 60 by 8, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 57310.87
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 57310.875
If we subtract 40 from 40, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 8 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 57310.875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 57310.875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 57310.875 with a remainder of 0.0.
