We look at the division of 12395187 by 99 
Let's see how many times 99 fits into 12395187.

On to step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 99

Step 2:
99 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 99

Step 3:
The number 99 fits into 123 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 99 from 123 leaves us with 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 99

Step 4:
The number 99 fits into 249 2 times, leaving a remainder of 51.
The next digit of our result is 2. 
Result so far: 12.0
If we take 198 away from 249, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 99

Moving on to step 5:
The number 99 fits into 515 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Deduct 495 from 515 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 99

Advancing to step 6:
When dividing 201 by 99, we get 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 1252.0
Subtract 198 from 201 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 99

Advancing to step 7:
99 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 12520.0
The remainder is 38 after subtracting 0 from 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 99

Going ahead to step 8:
387 divided by 99 is 3 with a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 125203.0
Deduct 297 from 387 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
900 divided by 99 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 125203.9
If we subtract 891 from 900, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
When dividing 90 by 99, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 125203.9
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 11:
When dividing 900 by 99, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 125203.909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
When dividing 90 by 99, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 125203.909
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 13:
When dividing 900 by 99, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 125203.90909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
99 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 125203.90909
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
900 divided by 99 is 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 125203.9090909
Subtract 891 from 900 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 16:
99 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 125203.9090909
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 125203.9090909 with a remaining 9e-08.
