We're dividing 805397 by 15 
Our goal is to divide 805397 by 15.

On to step 1:
15 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 15

On to step 2:
The number 15 fits into 80 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 75 from 80 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 15

On to step 3:
55 divided by 15 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
The remainder is 10 after subtracting 45 from 55.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 15

On to step 4:
103 divided by 15 is 6 with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 536.0
Subtracting 90 from 103 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 15

Going ahead to step 5:
15 goes into 139 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 5369.0
Deduct 135 from 139 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 15

On to step 6:
When dividing 47 by 15, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 53693.0
If we take 45 away from 47, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 15, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 53693.1
If we subtract 15 from 20, we 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 8:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 53693.13
If we subtract 45 from 50, we 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.

Moving on to step 9:
50 divided by 15 is 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 53693.133
If we subtract 45 from 50, we 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.

The quotient of the division is 53693.133, and the remainder is 0.0005.
