99479 ÷ 90 
We're looking to find how many times 90 goes into 99479.

Step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 90

Step 2:
90 goes into 99 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 90 from 99, we get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 90

Advancing to step 3:
90 can be fit into 94 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 90 from 94 leaves us with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 90

Moving on to step 4:
If we divide 47 by 90, we get 0 and a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
If we subtract 0 from 47, we get 47.
Fetch the next digit (9) from the dividend, attach it to 47 and continue: 479 / 90

Advancing to step 5:
479 divided by 90 is 5 with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 1105.0
Deduct 450 from 479 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 6:
90 can be fit into 290 3 times, resulting in a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 1105.3
Subtract 270 from 290 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.

On to step 7:
90 goes into 200 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 1105.32
Deduct 180 from 200 and we're left 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.

Step 8:
90 can be fit into 200 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 1105.322
If we take 180 away from 200, we end up 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.

After the division, we end up with 1105.322 and a remainder of 0.002.
