We look at the division of 288342 by 20 
We're looking to find how many times 20 goes into 288342.

On to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 20

On to step 2:
20 goes into 28 1 times with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 20 from 28, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 20

Let's proceed to step 3:
When dividing 88 by 20, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 80 from 88, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 20

On to step 4:
20 can be fit into 83 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 144.0
Deduct 80 from 83 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 20

Advancing to step 5:
20 goes into 34 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1441.0
If we take 20 away from 34, we end up with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 20

Moving on to step 6:
When dividing 142 by 20, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 14417.0
The remainder is 2 after subtracting 140 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 20 fits into 20 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 14417.1
The remainder is 0 after subtracting 20 from 20.
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 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14417.1
Deduct 0 from 0 and we're left 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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14417.1
If we take 0 away from 0, 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.

The final result is 14417.1 with a remainder of 0.0.
