We divide 797665 by 20
We want to figure out the number of times 797665 can be divided by 20.

Advancing to step 1:
7 divided by 20 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 20

Let's proceed to step 2:
If we divide 79 by 20, we get 3 and a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 79, we end up with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 20

Let's proceed to step 3:
If we divide 197 by 20, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 180 from 197 and we're left with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 20

Step 4:
When dividing 176 by 20, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 398.0
Subtract 160 from 176 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 20

Moving on to step 5:
The number 20 fits into 166 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 3988.0
Deduct 160 from 166 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 20

On to step 6:
65 divided by 20 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 39883.0
Deduct 60 from 65 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 20, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 39883.2
Subtract 40 from 50 to get 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:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 39883.25
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.

Moving on to step 9:
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: 39883.25
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 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 39883.25
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.

The final result is 39883.25 with a remainder of 0.0.
