743 ÷ 20 
Our goal is to divide 743 by 20.

On to step 1:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 20

Advancing to step 2:
When dividing 74 by 20, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 60 from 74, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 20

Moving on to step 3:
When dividing 143 by 20, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 3 after subtracting 140 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 4:
30 divided by 20 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 37.1
Subtracting 20 from 30 leaves us 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.

Moving on to step 5:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 37.15
If we subtract 100 from 100, 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.

Let's proceed to step 6:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37.15
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.

Moving on to step 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37.15
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.

The final outcome is 37.15, with a leftover of 0.0.
