We're dividing 153566 by 20 
Our goal is to divide 153566 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.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 20

Going ahead to step 2:
20 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 20

Let's proceed to step 3:
20 can be fit into 153 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 140 away from 153, we end up with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 20

Step 4:
The number 20 fits into 135 6 times, leaving a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
The remainder is 15 after subtracting 120 from 135.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 20

Advancing to step 5:
156 divided by 20 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 767.0
If we take 140 away from 156, we end up with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 20

Going ahead to step 6:
The number 20 fits into 166 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 7678.0
If we subtract 160 from 166, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 7678.3
If we subtract 60 from 60, 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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7678.3
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.

On 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: 7678.3
The remainder is 0 after subtracting 0 from 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 7678.3 with a balance of 0.0.
