Let's divide 143398 by 20
We're looking to find how many times 20 goes into 143398.

Let's proceed to step 1:
1 divided by 20 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 20

Let's proceed to step 2:
When dividing 14 by 20, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 20

Advancing to step 3:
If we divide 143 by 20, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 140 away from 143, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 20

Step 4:
20 can be fit into 33 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtract 20 from 33 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 20

On to step 5:
139 divided by 20 is 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 716.0
If we subtract 120 from 139, we get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 20

On to step 6:
198 divided by 20 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 7169.0
If we subtract 180 from 198, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 7169.9
Subtracting 180 from 180 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.

Advancing to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7169.9
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7169.9
Subtract 0 from 0 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.

In conclusion, the division gives 7169.9 with a balance of 0.0.
