157171 divided by 99 
We're looking to find how many times 99 goes into 157171.

Moving on to step 1:
If we divide 1 by 99, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 99

Let's proceed to step 2:
15 divided by 99 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 99

Advancing to step 3:
99 can be fit into 157 1 times, resulting in a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 58 after subtracting 99 from 157.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 99

Step 4:
If we divide 581 by 99, we get 5 and a remainder of 86.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 495 from 581, we get 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 99

Let's proceed to step 5:
99 goes into 867 8 times with a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 158.0
The remainder is 75 after subtracting 792 from 867.
Bring next digit (1) of the dividend behind the 75 and repeat the process: 751 / 99

Advancing to step 6:
When dividing 751 by 99, we get 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 1587.0
The remainder is 58 after subtracting 693 from 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
If we divide 580 by 99, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 1587.5
Subtract 495 from 580 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 8:
If we divide 850 by 99, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 1587.58
If we take 792 away from 850, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
99 goes into 580 5 times with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 1587.585
Subtract 495 from 580 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
99 can be fit into 850 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 1587.5858
If we take 792 away from 850, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
The number 99 fits into 580 5 times, leaving a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 1587.58585
The remainder is 85 after subtracting 495 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
When dividing 850 by 99, we get 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 1587.585858
If we take 792 away from 850, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 13:
The number 99 fits into 580 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 1587.5858585
If we subtract 495 from 580, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 14:
99 can be fit into 850 8 times, resulting in a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 1587.58585858
Deduct 792 from 850 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 1587.58585858 with a remainder of 5.8e-08.
