We divide 646285 by 15
We're looking to find how many times 15 goes into 646285.

On to step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 15

Advancing to step 2:
15 goes into 64 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 60 from 64 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 15

Step 3:
46 divided by 15 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 1 after subtracting 45 from 46.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 15

Advancing to step 4:
The number 15 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 430.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 15

On to step 5:
128 divided by 15 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 4308.0
If we subtract 120 from 128, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 15

Moving on to step 6:
The number 15 fits into 85 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 43085.0
Subtracting 75 from 85 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 43085.6
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 43085.66
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 43085.66 with a remainder of 0.01.
