We're dividing 305702 by 15 
We want to figure out the number of times 305702 can be divided by 15.

On to step 1:
15 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 15

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
Deduct 30 from 30 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

On to step 3:
The number 15 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Going ahead to step 4:
57 divided by 15 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 203.0
If we take 45 away from 57, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 15

On to step 5:
If we divide 120 by 15, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 2038.0
The remainder is 0 after subtracting 120 from 120.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 15

Advancing to step 6:
2 divided by 15 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 20380.0
Subtract 0 from 2 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 15, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 20380.1
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.

Step 8:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 20380.13
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.

Let's proceed to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 20380.133
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 20380.133, and the remainder is 0.0005.
