We're dividing 916904 by 90 
We want to figure out the number of times 916904 can be divided by 90.

On to step 1:
90 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 90

On to step 2:
The number 90 fits into 91 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 90 from 91 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 90

Going ahead to step 3:
When dividing 16 by 90, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 16, we get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 90

Going ahead to step 4:
The number 90 fits into 169 1 times, leaving a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we take 90 away from 169, we end up with 79.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 90

Moving on to step 5:
If we divide 790 by 90, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 1018.0
If we take 720 away from 790, we end up with 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 90

Advancing to step 6:
When dividing 704 by 90, we get 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 10187.0
Deduct 630 from 704 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
When dividing 740 by 90, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 10187.8
Subtract 720 from 740 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 10187.82
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 10187.822
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 10187.822, and the remainder is 0.002.
