We look at the division of 457829 by 15 
We're looking to find how many times 15 goes into 457829.

Let's proceed to step 1:
4 divided by 15 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 15

Moving on to step 2:
45 divided by 15 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 45 from 45 to get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 15

Advancing to step 3:
7 divided by 15 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 15

Going ahead to step 4:
When dividing 78 by 15, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 305.0
The remainder is 3 after subtracting 75 from 78.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 15

Advancing to step 5:
When dividing 32 by 15, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 3052.0
If we take 30 away from 32, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 15

Let's proceed to step 6:
If we divide 29 by 15, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 30521.0
Deduct 15 from 29 and we're left with 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.
Use 9 as the next digit of our solution. 
Result so far: 30521.9
If we take 135 away from 140, we end up 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.

Moving on to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 30521.93
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.

Advancing to step 9:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 30521.933
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.

Our division results in 30521.933 with a remaining 0.0005.
