We're dividing 792457 by 20 
We want to divide 792457 by 20.

Let's proceed to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 20

Step 2:
79 divided by 20 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 60 from 79 and we're left with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 20

Moving on to step 3:
When dividing 192 by 20, we get 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 180 away from 192, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 20

Moving on to step 4:
If we divide 124 by 20, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 396.0
Deduct 120 from 124 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 20

On to step 5:
When dividing 45 by 20, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 3962.0
Subtracting 40 from 45 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 20

Let's proceed to step 6:
The number 20 fits into 57 2 times, leaving a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 39622.0
Deduct 40 from 57 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
When dividing 170 by 20, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 39622.8
If we take 160 away from 170, 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.

Step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 39622.85
If we subtract 100 from 100, we 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.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39622.85
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.

Advancing to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39622.85
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 39622.85 with a remaining 0.0.
