Let's divide 455949 by 8
Our goal is to divide 455949 by 8.

Advancing to step 1:
8 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 8

Step 2:
45 divided by 8 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 5 after subtracting 40 from 45.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 8

Step 3:
If we divide 55 by 8, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 48 from 55 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 8

Step 4:
The number 8 fits into 79 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 569.0
Subtracting 72 from 79 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 8

On to step 5:
The number 8 fits into 74 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 5699.0
If we take 72 away from 74, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 8

Step 6:
29 divided by 8 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 56993.0
If we subtract 24 from 29, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
8 goes into 50 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 56993.6
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 8 fits into 20 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 56993.62
The remainder is 4 after subtracting 16 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 8 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 56993.625
Deduct 40 from 40 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.

Going ahead 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: 56993.625
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.

Step 11:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 56993.625
If we subtract 0 from 0, 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.

The final outcome is 56993.625, with a leftover of 0.0.
