We're dividing 408874 by 1 
We want to figure out the number of times 408874 can be divided by 1.

Step 1:
1 goes into 4 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 4 from 4, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Moving on to step 2:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Let's proceed to step 3:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 408.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Going ahead to step 4:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 4088.0
Subtract 8 from 8 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Let's proceed to step 5:
1 can be fit into 7 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 40887.0
Deduct 7 from 7 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Step 6:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 408874.0
Subtracting 4 from 4 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.

Moving on to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 408874.0
If we take 0 away from 0, we end up 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 8:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 408874.0
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.

The final outcome is 408874.0, with a leftover of 0.0.
