We look at the division of 3508 by 20 
Let's see how many times 20 fits into 3508.

Going ahead to step 1:
3 divided by 20 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 20

Advancing to step 2:
If we divide 35 by 20, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 20 from 35 and we're left with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 20

Let's proceed to step 3:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 140 from 150 to get 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 20

On to step 4:
If we divide 108 by 20, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
Deduct 100 from 108 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 5:
If we divide 80 by 20, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 175.4
Subtracting 80 from 80 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.

On to step 6:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 175.4
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.

Advancing to step 7:
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: 175.4
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.

In conclusion, the division gives 175.4 with a balance of 0.0.
