We're dividing 64492 by 20 
We're looking to find how many times 20 goes into 64492.

Going ahead to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 20

Step 2:
20 can be fit into 64 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 20

On to step 3:
20 can be fit into 44 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 32.0
If we take 40 away from 44, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 20

Step 4:
20 can be fit into 49 2 times, resulting in a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 322.0
The remainder is 9 after subtracting 40 from 49.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 20

Moving on to step 5:
20 can be fit into 92 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 3224.0
The remainder is 12 after subtracting 80 from 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 6:
20 goes into 120 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 3224.6
If we take 120 away from 120, 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.

Going ahead to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3224.6
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.

Step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3224.6
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 3224.6 with a balance of 0.0.
