Let's divide 655074 by 81
The aim is to understand the frequency of 81 in 655074.

On to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 81

Moving on to step 2:
If we divide 65 by 81, we get 0 and a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 81

Moving on to step 3:
655 divided by 81 is 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 7 after subtracting 648 from 655.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 81

Moving on to step 4:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 80.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 81

Let's proceed to step 5:
81 can be fit into 707 8 times, resulting in a remainder of 59.
The number 8 becomes the next digit in our result. 
Result so far: 808.0
The remainder is 59 after subtracting 648 from 707.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 81

Moving on to step 6:
If we divide 594 by 81, we get 7 and a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 8087.0
If we subtract 567 from 594, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
81 goes into 270 3 times with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 8087.3
The remainder is 27 after subtracting 243 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
The number 81 fits into 270 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 8087.33
Subtract 243 from 270 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 8087.33 and a remainder of 0.027.
