Let's divide 404158 by 1
We're looking to find how many times 1 goes into 404158.

Going ahead to step 1:
When dividing 4 by 1, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 4 from 4 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Moving on to step 2:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Moving on to step 3:
When dividing 4 by 1, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 404.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Step 4:
When dividing 1 by 1, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 4041.0
The remainder is 0 after subtracting 1 from 1.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

On to step 5:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40415.0
Subtract 5 from 5 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Going ahead to step 6:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 404158.0
The remainder is 0 after subtracting 8 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
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: 404158.0
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.

Going ahead to step 8:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 404158.0
The remainder is 0 after subtracting 0 from 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 404158.0 with a remainder of 0.0.
