661761 divided by 20 
Our goal is to divide 661761 by 20.

Moving on to step 1:
20 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 20

Let's proceed to step 2:
If we divide 66 by 20, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 60 from 66 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 20

Going ahead to step 3:
61 divided by 20 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 60 away from 61, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 20

Step 4:
20 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 330.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 20

Going ahead to step 5:
The number 20 fits into 176 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3308.0
Subtracting 160 from 176 leaves us with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 20

Going ahead to step 6:
20 goes into 161 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 33088.0
Subtracting 160 from 161 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
20 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 33088.0
If we take 0 away from 10, we end up 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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 33088.05
Subtracting 100 from 100 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 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33088.05
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.

Moving on to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33088.05
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.

In conclusion, the division gives 33088.05 with a balance of 0.0.
