904094 ÷ 15 
We want to figure out the number of times 904094 can be divided by 15.

Going ahead to step 1:
9 divided by 15 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 15

On to step 2:
When dividing 90 by 15, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 90 from 90, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 15

Moving on to step 3:
The number 15 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 15

Moving on to step 4:
The number 15 fits into 40 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 602.0
The remainder is 10 after subtracting 30 from 40.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 15

Moving on to step 5:
15 goes into 109 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 6027.0
Subtract 105 from 109 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 15

Advancing to step 6:
The number 15 fits into 44 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 60272.0
If we subtract 30 from 44, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 15, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 60272.9
If we subtract 135 from 140, 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.

Going ahead to step 8:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 60272.93
Deduct 45 from 50 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.

On to step 9:
15 goes into 50 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 60272.933
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 60272.933, and the remainder is 0.0005.
