We're dividing 620463 by 15 
We're looking to find how many times 15 goes into 620463.

Advancing to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 15

Moving on to step 2:
62 divided by 15 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 60 from 62 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 15

Step 3:
15 goes into 20 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
The remainder is 5 after subtracting 15 from 20.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 15

Let's proceed to step 4:
15 can be fit into 54 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 413.0
If we take 45 away from 54, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 15

Advancing to step 5:
15 can be fit into 96 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 4136.0
Subtracting 90 from 96 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 15

On to step 6:
The number 15 fits into 63 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 41364.0
Deduct 60 from 63 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 15, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 41364.2
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41364.2
If we take 0 away from 0, we end up 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.

Let's proceed to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41364.2
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.

Our division results in 41364.2 with a remaining 0.0.
