188171 ÷ 99 
We want to figure out the number of times 188171 can be divided by 99.

On 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
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 99

Advancing to step 2:
99 can be fit into 18 0 times, resulting in a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 99

Advancing to step 3:
99 can be fit into 188 1 times, resulting in a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 89 after subtracting 99 from 188.
Bring next digit (1) of the dividend behind the 89 and repeat the process: 891 / 99

Advancing to step 4:
The number 99 fits into 891 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 891 away from 891, we end up with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 99

Moving on to step 5:
The number 99 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 190.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 99

Going ahead to step 6:
71 divided by 99 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 1900.0
Deduct 0 from 71 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
If we divide 710 by 99, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 1900.7
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
99 goes into 170 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 1900.71
Deduct 99 from 170 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
710 divided by 99 is 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 1900.717
If we subtract 693 from 710, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
170 divided by 99 is 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 1900.7171
Subtracting 99 from 170 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 11:
The number 99 fits into 710 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 1900.71717
Subtracting 693 from 710 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
99 goes into 170 1 times with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1900.717171
Subtract 99 from 170 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 13:
710 divided by 99 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 1900.7171717
Subtracting 693 from 710 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
The number 99 fits into 170 1 times, leaving a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1900.71717171
Deduct 99 from 170 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

In conclusion, the division gives 1900.71717171 with a balance of 7.1e-08.
