527012 ÷ 20 
The aim is to understand the frequency of 20 in 527012.

On to step 1:
20 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 20

Going ahead to step 2:
20 goes into 52 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 40 away from 52, we end up with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 20

Moving on to step 3:
127 divided by 20 is 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 26.0
The remainder is 7 after subtracting 120 from 127.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 20

Step 4:
The number 20 fits into 70 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 263.0
Subtract 60 from 70 to get 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 20

Let's proceed to step 5:
If we divide 101 by 20, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 2635.0
Subtract 100 from 101 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 20

Step 6:
20 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 26350.0
Subtract 0 from 12 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
The number 20 fits into 120 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 26350.6
If we take 120 away from 120, 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.

Advancing 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: 26350.6
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.

Moving on to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26350.6
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.

After the division, we end up with 26350.6 and a remainder of 0.0.
