779670 divided by 20 
The aim is to understand the frequency of 20 in 779670.

Let's proceed to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 20

Step 2:
If we divide 77 by 20, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 60 from 77, we get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 20

Going ahead to step 3:
When dividing 179 by 20, we get 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 160 from 179 to get 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 20

Let's proceed to step 4:
20 can be fit into 196 9 times, resulting in a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 389.0
Deduct 180 from 196 and we're left with 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 20

Step 5:
If we divide 167 by 20, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 3898.0
Subtracting 160 from 167 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 20

Going ahead to step 6:
If we divide 70 by 20, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 38983.0
Subtracting 60 from 70 leaves us 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.

Going ahead to step 7:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 38983.5
Subtracting 100 from 100 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.

Moving on to step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 38983.5
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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 38983.5
If we subtract 0 from 0, 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.

The final result is 38983.5 with a remainder of 0.0.
