Let's divide 189913 by 99
We want to figure out the number of times 189913 can be divided by 99.

On to step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 99

Going ahead to step 2:
99 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 99

Let's proceed to step 3:
The number 99 fits into 189 1 times, leaving a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 99 from 189 to get 90.
Append the next digit (9) from the dividend to 90 and continue with: 909 / 99

Moving on to step 4:
If we divide 909 by 99, we get 9 and a remainder of 18.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 18 after subtracting 891 from 909.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 99

On to step 5:
99 can be fit into 181 1 times, resulting in a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
If we take 99 away from 181, we end up with 82.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 99

Moving on to step 6:
When dividing 823 by 99, we get 8 with a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 1918.0
The remainder is 31 after subtracting 792 from 823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
310 divided by 99 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1918.3
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
130 divided by 99 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1918.31
The remainder is 31 after subtracting 99 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
310 divided by 99 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1918.313
Deduct 297 from 310 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
130 divided by 99 is 1 with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1918.3131
The remainder is 31 after subtracting 99 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
When dividing 310 by 99, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 1918.31313
If we subtract 297 from 310, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
The number 99 fits into 130 1 times, leaving a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1918.313131
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
310 divided by 99 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1918.3131313
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
When dividing 130 by 99, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1918.31313131
If we take 99 away from 130, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 1918.31313131 with a remainder of 3.1e-08.
