We're dividing 897987 by 20 
The aim is to understand the frequency of 20 in 897987.

Moving on to step 1:
20 goes into 8 0 times with 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.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 20

Advancing to step 2:
20 goes into 89 4 times with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 80 from 89 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 20

Step 3:
20 goes into 97 4 times with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 80 from 97 leaves us with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 20

Going ahead to step 4:
The number 20 fits into 179 8 times, leaving a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 448.0
Deduct 160 from 179 and we're left with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 20

Moving on to step 5:
If we divide 198 by 20, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 4489.0
Subtract 180 from 198 to get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 20

Moving on to step 6:
The number 20 fits into 187 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 44899.0
Deduct 180 from 187 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
20 goes into 70 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 44899.3
If we take 60 away from 70, we end up 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.

Let's proceed to 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: 44899.35
Subtract 100 from 100 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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 44899.35
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.

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: 44899.35
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.

The final outcome is 44899.35, with a leftover of 0.0.
