143844 divided by 20 
We want to divide 143844 by 20.

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
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

On to step 2:
20 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 20

Let's proceed to step 3:
20 can be fit into 143 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 140 from 143 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 20

Step 4:
When dividing 38 by 20, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 20 from 38 and we're left with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 20

Step 5:
184 divided by 20 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 719.0
The remainder is 4 after subtracting 180 from 184.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

Step 6:
20 can be fit into 44 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 7192.0
Deduct 40 from 44 and we're left 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 7:
40 divided by 20 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 7192.2
Subtract 40 from 40 to 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.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7192.2
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.

Step 9:
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: 7192.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 7192.2 with a remainder of 0.0.
