We're dividing 171604 by 99 
Let's see how many times 99 fits into 171604.

Moving on to step 1:
When dividing 1 by 99, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 99

Step 2:
If we divide 17 by 99, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 99

Step 3:
171 divided by 99 is 1 with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 99 from 171 and we're left with 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 99

Moving on to step 4:
When dividing 726 by 99, we get 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 693 from 726 to get 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 99

Let's proceed to step 5:
The number 99 fits into 330 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
Subtracting 297 from 330 leaves us with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 99

Advancing to step 6:
The number 99 fits into 334 3 times, leaving a remainder of 37.
The next digit of our result is 3. 
Result so far: 1733.0
Deduct 297 from 334 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
If we divide 370 by 99, we get 3 and a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 1733.3
The remainder is 73 after subtracting 297 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 8:
730 divided by 99 is 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 1733.37
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
370 divided by 99 is 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 1733.373
The remainder is 73 after subtracting 297 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 10:
99 goes into 730 7 times with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 1733.3737
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
When dividing 370 by 99, we get 3 with a remainder of 73.
The next digit of our result is 3. 
Result so far: 1733.37373
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 12:
The number 99 fits into 730 7 times, leaving a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 1733.373737
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
99 goes into 370 3 times with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 1733.3737373
Subtracting 297 from 370 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 14:
99 can be fit into 730 7 times, resulting in a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 1733.37373737
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 1733.37373737 and a remainder of 3.7e-08.
