993104 ÷ 90 
We want to figure out the number of times 993104 can be divided by 90.

Moving on to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 90

Going ahead to step 2:
90 can be fit into 99 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 90 from 99 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 90

On to step 3:
90 can be fit into 93 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 90 away from 93, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 90

Advancing to step 4:
If we divide 31 by 90, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 90

On to step 5:
90 can be fit into 310 3 times, resulting in a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 1103.0
If we take 270 away from 310, we end up with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 90

Step 6:
90 can be fit into 404 4 times, resulting in a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 11034.0
The remainder is 44 after subtracting 360 from 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
If we divide 440 by 90, we get 4 and a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 11034.4
The remainder is 80 after subtracting 360 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
When dividing 800 by 90, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 11034.48
Subtract 720 from 800 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 11034.488
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 11034.488 with a remaining 0.008.
