Let's divide 798819 by 15
We're looking to find how many times 15 goes into 798819.

On to step 1:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 15

Moving on to step 2:
79 divided by 15 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 75 from 79 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 15

Step 3:
15 can be fit into 48 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 3 after subtracting 45 from 48.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 15

Let's proceed to step 4:
The number 15 fits into 38 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 532.0
Subtracting 30 from 38 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 15

Let's proceed to step 5:
The number 15 fits into 81 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 5325.0
Subtracting 75 from 81 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 15

Going ahead to step 6:
15 goes into 69 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 53254.0
If we subtract 60 from 69, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 divided by 15 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 53254.6
Deduct 90 from 90 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.

Step 8:
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: 53254.6
Deduct 0 from 0 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.

Advancing to step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 53254.6
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.

After the division, we end up with 53254.6 and a remainder of 0.0.
