We're dividing 16699 by 90 
We're looking to find how many times 90 goes into 16699.

Going ahead to step 1:
90 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 90

On to step 2:
The number 90 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 90

Step 3:
166 divided by 90 is 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 90 from 166, we get 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 90

Moving on to step 4:
The number 90 fits into 769 8 times, leaving a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 49 after subtracting 720 from 769.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 90

Going ahead to step 5:
90 can be fit into 499 5 times, resulting in a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 185.0
If we take 450 away from 499, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 6:
90 can be fit into 490 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 185.5
Subtract 450 from 490 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
90 can be fit into 400 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 185.54
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 185.544
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 185.544 with a remainder of 0.004.
