171669 divided by 99 
We want to divide 171669 by 99.

Let's proceed to step 1:
99 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 99

Advancing to step 2:
17 divided by 99 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 99

Advancing to step 3:
99 goes into 171 1 times with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 99 from 171, we get 72.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 99

Advancing to step 4:
726 divided by 99 is 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 693 from 726, we get 33.
Bring next digit (6) of the dividend behind the 33 and repeat the process: 336 / 99

Going ahead to step 5:
99 can be fit into 336 3 times, resulting in a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
If we subtract 297 from 336, we get 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 99

Step 6:
99 can be fit into 399 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 1734.0
The remainder is 3 after subtracting 396 from 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
99 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1734.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
300 divided by 99 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1734.03
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
The number 99 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1734.03
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1734.0303
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
If we divide 30 by 99, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1734.0303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
99 goes into 300 3 times with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1734.030303
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
If we divide 30 by 99, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1734.030303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
99 goes into 300 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 1734.03030303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 1734.03030303 with a remaining 3e-09.
