We divide 405437 by 15
Let's see how many times 15 fits into 405437.

Going ahead to step 1:
The number 15 fits into 4 0 times, leaving 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.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 15

Let's proceed to step 2:
15 can be fit into 40 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 30 from 40 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 15

On to step 3:
When dividing 105 by 15, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 105 from 105 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 15

Advancing to step 4:
If we divide 4 by 15, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 270.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 15

Advancing to step 5:
43 divided by 15 is 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 2702.0
If we subtract 30 from 43, we get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 15

Let's proceed to step 6:
When dividing 137 by 15, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 27029.0
If we take 135 away from 137, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 15 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 27029.1
Subtracting 15 from 20 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 27029.13
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 27029.133
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 27029.133 with a remaining 0.0005.
