406605 ÷ 1 
Let's see how many times 1 fits into 406605.

Step 1:
If we divide 4 by 1, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Going ahead to step 2:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 0 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Advancing to step 3:
If we divide 6 by 1, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 406.0
Subtract 6 from 6 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Advancing to step 4:
6 divided by 1 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 4066.0
If we subtract 6 from 6, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

On to step 5:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40660.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

On to step 6:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 406605.0
The remainder is 0 after subtracting 5 from 5.
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:
1 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: 406605.0
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.

Let's proceed to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 406605.0
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.

The final outcome is 406605.0, with a leftover of 0.0.
