Let's divide 589173 by 20
The aim is to understand the frequency of 20 in 589173.

On to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 20

Going ahead to step 2:
The number 20 fits into 58 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 18 after subtracting 40 from 58.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 20

Step 3:
When dividing 189 by 20, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we take 180 away from 189, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 20

On to step 4:
20 goes into 91 4 times with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 294.0
The remainder is 11 after subtracting 80 from 91.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 20

Step 5:
117 divided by 20 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 2945.0
Subtracting 100 from 117 leaves us with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 20

Advancing to step 6:
When dividing 173 by 20, we get 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 29458.0
If we take 160 away from 173, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
If we divide 130 by 20, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 29458.6
Deduct 120 from 130 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.

Advancing to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 29458.65
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.

Going ahead to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29458.65
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.

Step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29458.65
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 outcome is 29458.65, with a leftover of 0.0.
