Let's divide 402016 by 15
Let's see how many times 15 fits into 402016.

On to step 1:
4 divided by 15 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 15

On to step 2:
When dividing 40 by 15, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 30 from 40, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 15

Step 3:
15 goes into 102 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we subtract 90 from 102, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 15

On to step 4:
15 goes into 120 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
Deduct 120 from 120 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 15

Going ahead to step 5:
If we divide 1 by 15, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 2680.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 15

Step 6:
15 goes into 16 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 26801.0
If we take 15 away from 16, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 15 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 26801.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 26801.06
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 26801.066
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 26801.066, and the remainder is 0.001.
