Let's divide 799485 by 20
The aim is to understand the frequency of 20 in 799485.

Let's proceed to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 20

Let's proceed to step 2:
When dividing 79 by 20, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 60 from 79, we get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 20

Advancing to step 3:
20 can be fit into 199 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 19 after subtracting 180 from 199.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 20

Going ahead to step 4:
The number 20 fits into 194 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 399.0
The remainder is 14 after subtracting 180 from 194.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 20

Advancing to step 5:
When dividing 148 by 20, we get 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 3997.0
If we take 140 away from 148, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 20

Moving on to step 6:
20 goes into 85 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 39974.0
Subtract 80 from 85 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to 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: 39974.2
Deduct 40 from 50 and we're left 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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 39974.25
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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 39974.25
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.

Advancing to step 10:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 39974.25
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 39974.25 with a remainder of 0.0.
