We divide 406086 by 15
Our goal is to divide 406086 by 15.

On to step 1:
15 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 15

Going ahead to step 2:
40 divided by 15 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 10 after subtracting 30 from 40.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 15

Step 3:
15 can be fit into 106 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Deduct 105 from 106 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 15

Moving on to step 4:
15 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 270.0
If we subtract 0 from 10, we get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 15

Step 5:
When dividing 108 by 15, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 2707.0
Subtract 105 from 108 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 15

Going ahead to step 6:
When dividing 36 by 15, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 27072.0
Subtracting 30 from 36 leaves us 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.

Step 7:
15 goes into 60 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 27072.4
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.

Going ahead to step 8:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27072.4
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.

Let's proceed to step 9:
15 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27072.4
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.

The quotient of the division is 27072.4, and the remainder is 0.0.
