We look at the division of 302170 by 99 
We're looking to find how many times 99 goes into 302170.

Advancing to step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 99

Going ahead to step 2:
30 divided by 99 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 99

Step 3:
If we divide 302 by 99, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 297 from 302 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 99

Going ahead to step 4:
When dividing 51 by 99, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 99

Moving on to step 5:
When dividing 517 by 99, we get 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 305.0
Deduct 495 from 517 and we're left with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 99

Step 6:
When dividing 220 by 99, we get 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 3052.0
Subtract 198 from 220 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
The number 99 fits into 220 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 3052.2
Subtract 198 from 220 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
99 can be fit into 220 2 times, resulting in a remainder of 22.
The next digit of our result is 2. 
Result so far: 3052.22
Subtracting 198 from 220 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 3052.22 with a remaining 0.022.
