755429 ÷ 20 
Our goal is to divide 755429 by 20.

Let's proceed to step 1:
20 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 20

Advancing to step 2:
20 can be fit into 75 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 75 leaves us with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 20

Moving on to step 3:
20 goes into 155 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 140 from 155 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 20

Step 4:
20 can be fit into 154 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 377.0
Subtracting 140 from 154 leaves us with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 20

Step 5:
20 can be fit into 142 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 3777.0
Deduct 140 from 142 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 20

On to step 6:
If we divide 29 by 20, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 37771.0
Subtract 20 from 29 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 20 fits into 90 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 37771.4
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 37771.45
If we take 100 away from 100, 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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37771.45
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.

Going ahead to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37771.45
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 37771.45, with a leftover of 0.0.
