617494 ÷ 15 
We want to figure out the number of times 617494 can be divided by 15.

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
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 15

On to step 2:
15 goes into 61 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 60 from 61 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 15

Let's proceed to step 3:
When dividing 17 by 15, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 41.0
If we take 15 away from 17, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 15

Moving on to step 4:
The number 15 fits into 24 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 411.0
If we subtract 15 from 24, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 15

Let's proceed to step 5:
99 divided by 15 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 4116.0
If we take 90 away from 99, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 15

Moving on to step 6:
When dividing 94 by 15, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 41166.0
If we subtract 90 from 94, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 15, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 41166.2
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 41166.26
Deduct 90 from 100 and we're left 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 9:
When dividing 100 by 15, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 41166.266
If we subtract 90 from 100, we get 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 41166.266 with a remainder of 0.001.
