680524 ÷ 20 
The aim is to understand the frequency of 20 in 680524.

Advancing to step 1:
6 divided by 20 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 20

Going ahead to step 2:
68 divided by 20 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 60 from 68 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 20

Advancing to step 3:
20 goes into 80 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 80 from 80 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 20

Going ahead to step 4:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 340.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 20

On to step 5:
20 can be fit into 52 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 3402.0
The remainder is 12 after subtracting 40 from 52.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 20

Let's proceed to step 6:
20 can be fit into 124 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 34026.0
Subtracting 120 from 124 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 20 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 34026.2
Subtracting 40 from 40 leaves us 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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34026.2
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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34026.2
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 34026.2 and a remainder of 0.0.
