We're dividing 142357 by 20 
We're looking to find how many times 20 goes into 142357.

Advancing to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 20

Moving on to step 2:
When dividing 14 by 20, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 20

Going ahead to step 3:
20 goes into 142 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 7.0
If we take 140 away from 142, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 20

On to step 4:
If we divide 23 by 20, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 20 from 23, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 20

Let's proceed to step 5:
20 can be fit into 35 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 711.0
The remainder is 15 after subtracting 20 from 35.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 20

Going ahead to step 6:
The number 20 fits into 157 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 7117.0
If we subtract 140 from 157, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
20 goes into 170 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 7117.8
If we take 160 away from 170, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7117.85
The remainder is 0 after subtracting 100 from 100.
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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 7117.85
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.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7117.85
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 7117.85 with a remaining 0.0.
