143098 ÷ 20 
We want to divide 143098 by 20.

Going ahead to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 20

Advancing to step 2:
20 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 20

Moving on to step 3:
143 divided by 20 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 140 from 143 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 20

Moving on to step 4:
20 goes into 30 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 71.0
Subtract 20 from 30 to get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 20

Going ahead to step 5:
109 divided by 20 is 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 715.0
If we subtract 100 from 109, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 20

Moving on to step 6:
The number 20 fits into 98 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 7154.0
The remainder is 18 after subtracting 80 from 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
20 can be fit into 180 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 7154.9
If we take 180 away from 180, 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.

Step 8:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7154.9
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7154.9
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.

Our division results in 7154.9 with a remaining 0.0.
