171912 divided by 99 
Our goal is to divide 171912 by 99.

Let's proceed to step 1:
99 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 99

On to 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

Advancing 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
If we take 99 away from 171, we end up with 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 99

Going ahead to step 4:
When dividing 729 by 99, we get 7 with a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 36 after subtracting 693 from 729.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 99

Advancing to step 5:
When dividing 361 by 99, we get 3 with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 173.0
Deduct 297 from 361 and we're left with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 99

Step 6:
642 divided by 99 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 1736.0
Subtracting 594 from 642 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
If we divide 480 by 99, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 1736.4
Subtract 396 from 480 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 8:
99 can be fit into 840 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1736.48
Subtracting 792 from 840 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
The number 99 fits into 480 4 times, leaving a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 1736.484
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
840 divided by 99 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1736.4848
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
If we divide 480 by 99, we get 4 and a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 1736.48484
If we take 396 away from 480, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
840 divided by 99 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 1736.484848
If we take 792 away from 840, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
When dividing 480 by 99, we get 4 with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 1736.4848484
Deduct 396 from 480 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 14:
840 divided by 99 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 1736.48484848
Subtract 792 from 840 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 1736.48484848, and the remainder is 4.8e-08.
