We're dividing 742764 by 20 
We're looking to find how many times 20 goes into 742764.

Going ahead to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 20

Advancing to step 2:
74 divided by 20 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 60 from 74 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 20

On to step 3:
If we divide 142 by 20, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 140 from 142 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 20

Let's proceed to step 4:
20 goes into 27 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 371.0
The remainder is 7 after subtracting 20 from 27.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 20

Moving on to step 5:
20 goes into 76 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 3713.0
The remainder is 16 after subtracting 60 from 76.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 20

Let's proceed to step 6:
20 can be fit into 164 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 37138.0
If we subtract 160 from 164, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 20 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 37138.2
Subtracting 40 from 40 leaves us 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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 37138.2
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.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37138.2
Subtracting 0 from 0 leaves us 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 37138.2 with a remainder of 0.0.
