We look at the division of 305706 by 15 
We want to figure out the number of times 305706 can be divided by 15.

Step 1:
The number 15 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 15

Step 2:
30 divided by 15 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 30 from 30, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 15

Advancing to step 3:
15 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Step 4:
57 divided by 15 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 203.0
Subtracting 45 from 57 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 15

Going ahead to step 5:
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: 2038.0
If we take 120 away from 120, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 15

Moving on to step 6:
If we divide 6 by 15, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 20380.0
Deduct 0 from 6 and we're left 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.

Going ahead to step 7:
15 goes into 60 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 20380.4
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:
When dividing 0 by 15, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20380.4
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.

Let's proceed to step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20380.4
The remainder is 0 after subtracting 0 from 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 final outcome is 20380.4, with a leftover of 0.0.
