We look at the division of 198780 by 13 
Let's see how many times 13 fits into 198780.

On to step 1:
The number 13 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 13

Going ahead to step 2:
The number 13 fits into 19 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 13 away from 19, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 13

Advancing to step 3:
The number 13 fits into 68 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 65 from 68 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 13

Step 4:
13 goes into 37 2 times with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 152.0
If we subtract 26 from 37, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 13

Step 5:
13 can be fit into 118 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 1529.0
Deduct 117 from 118 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 13

On to step 6:
10 divided by 13 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 15290.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
If we divide 100 by 13, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 15290.7
If we take 91 away from 100, we end up with 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 8:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 15290.76
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 13 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 15290.769
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 15290.7692
If we take 26 away from 30, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
13 goes into 40 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 15290.76923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15290.76923
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 13, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 15290.7692307
Deduct 91 from 100 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
When dividing 90 by 13, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 15290.76923076
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 15290.76923076 with a remaining 1.2e-08.
