We look at the division of 846263 by 15 
We want to figure out the number of times 846263 can be divided by 15.

Step 1:
When dividing 8 by 15, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 15

Advancing to step 2:
If we divide 84 by 15, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 9 after subtracting 75 from 84.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 15

On to step 3:
When dividing 96 by 15, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 56.0
Subtracting 90 from 96 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 15

Moving on to step 4:
62 divided by 15 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 564.0
If we subtract 60 from 62, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 15

On to step 5:
15 goes into 26 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 5641.0
Deduct 15 from 26 and we're left with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 15

Step 6:
113 divided by 15 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 56417.0
Subtract 105 from 113 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
80 divided by 15 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 56417.5
Deduct 75 from 80 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.

Advancing to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 56417.53
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.

On to step 9:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 56417.533
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 56417.533, and the remainder is 0.0005.
