Let's divide 491037 by 20
The aim is to understand the frequency of 20 in 491037.

Let's proceed to step 1:
20 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 20

Advancing to step 2:
The number 20 fits into 49 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 9 after subtracting 40 from 49.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 20

Step 3:
91 divided by 20 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 11 after subtracting 80 from 91.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 20

On to step 4:
When dividing 110 by 20, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 245.0
Subtract 100 from 110 to get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 20

Step 5:
When dividing 103 by 20, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 2455.0
If we subtract 100 from 103, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 20

Moving on to step 6:
The number 20 fits into 37 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 24551.0
Deduct 20 from 37 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.

Going ahead to step 7:
20 goes into 170 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 24551.8
Subtract 160 from 170 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.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 24551.85
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.

Advancing 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: 24551.85
Subtract 0 from 0 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 10:
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: 24551.85
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 24551.85, and the remainder is 0.0.
