Let's divide 306837 by 15
Let's see how many times 15 fits into 306837.

On to step 1:
If we divide 3 by 15, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 15

Going ahead to step 2:
The number 15 fits into 30 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 30 from 30 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 15

Step 3:
The number 15 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 15

Step 4:
68 divided by 15 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 204.0
The remainder is 8 after subtracting 60 from 68.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 15

Let's proceed to step 5:
The number 15 fits into 83 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 2045.0
Subtract 75 from 83 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 15

Going ahead to step 6:
The number 15 fits into 87 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 20455.0
Subtracting 75 from 87 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 20455.8
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20455.8
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.

Moving on to step 9:
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: 20455.8
If we subtract 0 from 0, we get 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 20455.8, and the remainder is 0.0.
