We're dividing 899001 by 20 
The aim is to understand the frequency of 20 in 899001.

Let's proceed to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 20

On to step 2:
When dividing 89 by 20, we get 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 9 after subtracting 80 from 89.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 20

Going ahead to step 3:
20 can be fit into 99 4 times, resulting in a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtract 80 from 99 to get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 20

Going ahead to step 4:
20 goes into 190 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 449.0
Subtracting 180 from 190 leaves us with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 20

Going ahead to step 5:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4495.0
Subtract 100 from 100 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 20

Going ahead to step 6:
If we divide 1 by 20, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 44950.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 20 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 44950.0
Subtract 0 from 10 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:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 44950.05
If we take 100 away from 100, 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.

Moving on 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: 44950.05
Subtracting 0 from 0 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.

Advancing to step 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 44950.05
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 quotient of the division is 44950.05, and the remainder is 0.0.
