904739 ÷ 9 
We want to figure out the number of times 904739 can be divided by 9.

On to step 1:
9 divided by 9 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 9 from 9, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 9

Moving on to step 2:
9 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 9

On to step 3:
The number 9 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 9

Step 4:
The number 9 fits into 47 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 1005.0
If we take 45 away from 47, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 9

Moving on to step 5:
When dividing 23 by 9, we get 2 with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 10052.0
The remainder is 5 after subtracting 18 from 23.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 9

Moving on to step 6:
9 can be fit into 59 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 100526.0
Subtracting 54 from 59 leaves us 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 7:
When dividing 50 by 9, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 100526.5
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.

On to step 8:
9 goes into 50 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 100526.55
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.

The quotient of the division is 100526.55, and the remainder is 0.005.
