606204 ÷ 81 
The aim is to understand the frequency of 81 in 606204.

Going ahead to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 81

Going ahead to step 2:
60 divided by 81 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 81

Let's proceed to step 3:
If we divide 606 by 81, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 567 from 606, we get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 81

Let's proceed to step 4:
The number 81 fits into 392 4 times, leaving a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 68 after subtracting 324 from 392.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 81

Advancing to step 5:
81 can be fit into 680 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 748.0
If we take 648 away from 680, we end up with 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 81

Let's proceed to step 6:
If we divide 324 by 81, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 7484.0
If we take 324 away from 324, 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 7:
81 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7484.0
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.

Step 8:
The number 81 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7484.0
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.

After the division, we end up with 7484.0 and a remainder of 0.0.
