Let's divide 154509 by 20
Our goal is to divide 154509 by 20.

Going ahead to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 20

Going ahead to step 2:
20 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 20

On to step 3:
If we divide 154 by 20, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 7.0
If we take 140 away from 154, we end up with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 20

On to step 4:
20 goes into 145 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtracting 140 from 145 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 20

Step 5:
The number 20 fits into 50 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 772.0
Deduct 40 from 50 and we're left with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 20

On to step 6:
If we divide 109 by 20, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 7725.0
Subtracting 100 from 109 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 7725.4
Deduct 80 from 90 and we're left 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.

Let's proceed to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7725.45
Deduct 100 from 100 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.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7725.45
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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7725.45
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.

In conclusion, the division gives 7725.45 with a balance of 0.0.
