We're dividing 448413 by 8 
We want to figure out the number of times 448413 can be divided by 8.

On to step 1:
8 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 8

Let's proceed to step 2:
8 can be fit into 44 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 40 from 44 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 8

Let's proceed to step 3:
When dividing 48 by 8, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 56.0
If we subtract 48 from 48, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 8

Let's proceed to step 4:
If we divide 4 by 8, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 560.0
If we take 0 away from 4, we end up with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 8

Let's proceed to step 5:
When dividing 41 by 8, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5605.0
If we take 40 away from 41, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 8

Step 6:
8 can be fit into 13 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 56051.0
Subtracting 8 from 13 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 8 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 56051.6
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 8 fits into 20 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 56051.62
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 56051.625
Subtracting 40 from 40 leaves us 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.

Step 10:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 56051.625
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.

Moving on to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 56051.625
Subtracting 0 from 0 leaves us 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 outcome is 56051.625, with a leftover of 0.0.
