We're dividing 408906 by 10 
We're looking to find how many times 10 goes into 408906.

Let's proceed to step 1:
When dividing 4 by 10, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 10

Step 2:
The number 10 fits into 40 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 40 from 40 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 10

Let's proceed to step 3:
If we divide 8 by 10, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 10

Going ahead to step 4:
10 can be fit into 89 8 times, resulting in a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 408.0
If we take 80 away from 89, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 10

Going ahead to step 5:
10 goes into 90 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 4089.0
Subtracting 90 from 90 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 10

Step 6:
10 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 40890.0
If we take 0 away from 6, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 10, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 40890.6
Deduct 60 from 60 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.

Step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40890.6
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.

Step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40890.6
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.

The final outcome is 40890.6, with a leftover of 0.0.
