We divide 649158 by 20
We want to figure out the number of times 649158 can be divided by 20.

Let's proceed to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 20

Moving on to step 2:
When dividing 64 by 20, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 60 from 64 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 20

Let's proceed to step 3:
The number 20 fits into 49 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 32.0
Deduct 40 from 49 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 20

Moving on to step 4:
The number 20 fits into 91 4 times, leaving a remainder of 11.
The next digit of our result is 4. 
Result so far: 324.0
If we take 80 away from 91, we end up with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 20

Step 5:
The number 20 fits into 115 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3245.0
Deduct 100 from 115 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 20

Moving on to step 6:
When dividing 158 by 20, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 32457.0
If we take 140 away from 158, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 20, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 32457.9
Deduct 180 from 180 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.

On to step 8:
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: 32457.9
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.

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: 32457.9
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.

Our division results in 32457.9 with a remaining 0.0.
