We're dividing 524740 by 20 
The aim is to understand the frequency of 20 in 524740.

Advancing to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 20

Going ahead to step 2:
52 divided by 20 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 40 away from 52, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 20

Moving on to step 3:
20 goes into 124 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 120 away from 124, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 20

Let's proceed to step 4:
When dividing 47 by 20, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 262.0
Deduct 40 from 47 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 20

On to step 5:
20 can be fit into 74 3 times, resulting in a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 2623.0
Subtract 60 from 74 to get 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 20

On to step 6:
The number 20 fits into 140 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 26237.0
If we subtract 140 from 140, 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 7:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26237.0
If we subtract 0 from 0, 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.

Let's proceed to step 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 26237.0
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.

The final result is 26237.0 with a remainder of 0.0.
