849349 ÷ 20 
The aim is to understand the frequency of 20 in 849349.

Advancing to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 20

Let's proceed to step 2:
When dividing 84 by 20, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 80 away from 84, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 20

Step 3:
If we divide 49 by 20, we get 2 and a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 9 after subtracting 40 from 49.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 20

On to step 4:
93 divided by 20 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 424.0
Subtract 80 from 93 to get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 20

Step 5:
If we divide 134 by 20, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 4246.0
Deduct 120 from 134 and we're left with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 20

Going ahead to step 6:
If we divide 149 by 20, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 42467.0
Deduct 140 from 149 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 42467.4
The remainder is 10 after subtracting 80 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 42467.45
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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42467.45
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.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 42467.45
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 quotient of the division is 42467.45, and the remainder is 0.0.
