Let's divide 131868 by 20
Let's see how many times 20 fits into 131868.

Going ahead to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 20

Moving on to step 2:
20 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 20

Let's proceed to step 3:
20 can be fit into 131 6 times, resulting in a remainder of 11.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 11 after subtracting 120 from 131.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 20

Going ahead to step 4:
When dividing 118 by 20, we get 5 with a remainder of 18.
The next digit of our result is 5. 
Result so far: 65.0
Subtract 100 from 118 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 20

Going ahead to step 5:
The number 20 fits into 186 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 659.0
If we subtract 180 from 186, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 20

Step 6:
20 can be fit into 68 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 6593.0
Deduct 60 from 68 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 20, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 6593.4
If we take 80 away from 80, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6593.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6593.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 6593.4 and a remainder of 0.0.
