725693 ÷ 20 
The aim is to understand the frequency of 20 in 725693.

Let's proceed to step 1:
20 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

Let's proceed to step 2:
The number 20 fits into 72 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 60 from 72 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 20

Step 3:
20 goes into 125 6 times with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 5 after subtracting 120 from 125.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 20

Advancing to step 4:
The number 20 fits into 56 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 362.0
Subtracting 40 from 56 leaves us with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 20

Let's proceed to step 5:
When dividing 169 by 20, we get 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 3628.0
If we subtract 160 from 169, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 20

On to step 6:
The number 20 fits into 93 4 times, leaving a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 36284.0
Subtracting 80 from 93 leaves us 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.

Let's proceed to step 7:
If we divide 130 by 20, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 36284.6
The remainder is 10 after subtracting 120 from 130.
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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 36284.65
Deduct 100 from 100 and we're left 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 9:
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: 36284.65
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.

Going ahead to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36284.65
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.

After the division, we end up with 36284.65 and a remainder of 0.0.
