Let's divide 726687 by 20
The aim is to understand the frequency of 20 in 726687.

Let's proceed to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

Let's proceed to step 2:
20 can be fit into 72 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 60 from 72 to get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 20

Going ahead to step 3:
126 divided by 20 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 36.0
Deduct 120 from 126 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 20

Advancing to step 4:
20 goes into 66 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 363.0
If we take 60 away from 66, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 20

Advancing to step 5:
20 goes into 68 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3633.0
Subtract 60 from 68 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 20

On to step 6:
The number 20 fits into 87 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 36334.0
Subtract 80 from 87 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
70 divided by 20 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 36334.3
Deduct 60 from 70 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.

On to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 36334.35
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36334.35
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.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36334.35
Deduct 0 from 0 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.

Our division results in 36334.35 with a remaining 0.0.
