We're dividing 171490 by 99 
We're looking to find how many times 99 goes into 171490.

Going ahead to step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 99

Step 2:
When dividing 17 by 99, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 99

Going ahead to step 3:
When dividing 171 by 99, we get 1 with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 99 from 171 to get 72.
Take the next digit (4) from the dividend and append it to 72, then repeat: 724 / 99

Moving on to step 4:
99 goes into 724 7 times with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 693 from 724, we get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 99

Moving on to step 5:
99 goes into 319 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 173.0
If we take 297 away from 319, we end up with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 99

Let's proceed to step 6:
If we divide 220 by 99, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 1732.0
Deduct 198 from 220 and we're left 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.

Going ahead 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: 1732.2
If we subtract 198 from 220, we 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.

Step 8:
220 divided by 99 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 1732.22
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.

The quotient of the division is 1732.22, and the remainder is 0.022.
