335789 ÷ 15 
We want to figure out the number of times 335789 can be divided by 15.

Step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 15

Let's proceed to step 2:
15 can be fit into 33 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 30 from 33 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 15

Let's proceed to step 3:
15 goes into 35 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 30 from 35, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 15

Going ahead to step 4:
15 goes into 57 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 223.0
Subtract 45 from 57 to get 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 15

Let's proceed to step 5:
If we divide 128 by 15, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 2238.0
Subtracting 120 from 128 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 15

Step 6:
When dividing 89 by 15, we get 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 22385.0
If we subtract 75 from 89, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
The number 15 fits into 140 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 22385.9
The remainder is 5 after subtracting 135 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to 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: 22385.93
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.

Going ahead to step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 22385.933
Deduct 45 from 50 and we're left 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.

The final result is 22385.933 with a remainder of 0.0005.
