We look at the division of 142064 by 20 
We want to divide 142064 by 20.

Let's proceed to step 1:
20 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to 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.
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.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 20

Moving on to step 3:
If we divide 142 by 20, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 140 from 142 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 20

Let's proceed to step 4:
20 goes into 20 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 20 from 20 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 20

On to step 5:
6 divided by 20 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 710.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 20

Advancing to step 6:
When dividing 64 by 20, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 7103.0
If we take 60 away from 64, we end up 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:
If we divide 40 by 20, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 7103.2
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7103.2
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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7103.2
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 outcome is 7103.2, with a leftover of 0.0.
