931861 divided by 15 
We want to figure out the number of times 931861 can be divided by 15.

Advancing to step 1:
15 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 15

Let's proceed to step 2:
The number 15 fits into 93 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 90 from 93 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 15

Going ahead to step 3:
15 can be fit into 31 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Deduct 30 from 31 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 15

On to step 4:
15 goes into 18 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 621.0
Subtracting 15 from 18 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 15

Step 5:
15 goes into 36 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 6212.0
The remainder is 6 after subtracting 30 from 36.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 15

Step 6:
If we divide 61 by 15, we get 4 and a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 62124.0
Deduct 60 from 61 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 15, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 62124.0
The remainder is 10 after subtracting 0 from 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 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 62124.06
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.

Let's proceed to step 9:
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: 62124.066
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.

The final outcome is 62124.066, with a leftover of 0.001.
