We divide 408187 by 39
We want to divide 408187 by 39.

Step 1:
39 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 39

Advancing to step 2:
40 divided by 39 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 39 from 40, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 39

Moving on to step 3:
If we divide 18 by 39, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 39

Advancing to step 4:
If we divide 181 by 39, we get 4 and a remainder of 25.
The next digit of our result is 4. 
Result so far: 104.0
If we take 156 away from 181, we end up with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 39

Step 5:
When dividing 258 by 39, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1046.0
If we subtract 234 from 258, we get 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 39

Let's proceed to step 6:
39 can be fit into 247 6 times, resulting in a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 10466.0
If we subtract 234 from 247, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
39 goes into 130 3 times with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 10466.3
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
39 goes into 130 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 10466.33
If we take 117 away from 130, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 10466.33 and a remainder of 0.013.
