We're dividing 486913 by 20 
We want to figure out the number of times 486913 can be divided by 20.

On to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 20

Advancing to step 2:
48 divided by 20 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 40 from 48, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 20

Moving on to step 3:
20 can be fit into 86 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 80 away from 86, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 20

Advancing to step 4:
69 divided by 20 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 243.0
Subtracting 60 from 69 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 20

Advancing to step 5:
The number 20 fits into 91 4 times, leaving a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 2434.0
The remainder is 11 after subtracting 80 from 91.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 20

Going ahead to step 6:
When dividing 113 by 20, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 24345.0
Subtract 100 from 113 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
130 divided by 20 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 24345.6
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 24345.65
Subtract 100 from 100 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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 24345.65
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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24345.65
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.

In conclusion, the division gives 24345.65 with a balance of 0.0.
