We divide 170371 by 99
We want to figure out the number of times 170371 can be divided by 99.

Step 1:
99 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 99

Let's proceed to step 2:
99 goes into 17 0 times 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.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 99

Advancing to step 3:
If we divide 170 by 99, we get 1 and a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 71 after subtracting 99 from 170.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 99

On to step 4:
99 goes into 713 7 times with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 20 after subtracting 693 from 713.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 99

Step 5:
99 can be fit into 207 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Deduct 198 from 207 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 99

Moving on to step 6:
When dividing 91 by 99, we get 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 1720.0
Deduct 0 from 91 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 7:
99 goes into 910 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 1720.9
Subtract 891 from 910 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
The number 99 fits into 190 1 times, leaving a remainder of 91.
Write down 1 as next digit of the result. 
Result so far: 1720.91
If we take 99 away from 190, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
If we divide 910 by 99, we get 9 and a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 1720.919
If we subtract 891 from 910, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
The number 99 fits into 190 1 times, leaving a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 1720.9191
Deduct 99 from 190 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 11:
99 goes into 910 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 1720.91919
Subtracting 891 from 910 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
99 can be fit into 190 1 times, resulting in a remainder of 91.
The next digit of our result is 1. 
Result so far: 1720.919191
If we take 99 away from 190, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 13:
If we divide 910 by 99, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 1720.9191919
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
The number 99 fits into 190 1 times, leaving a remainder of 91.
The next digit of our result is 1. 
Result so far: 1720.91919191
If we take 99 away from 190, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Our division results in 1720.91919191 with a remaining 9.1e-08.
