589005 divided by 81 
The aim is to understand the frequency of 81 in 589005.

Advancing to step 1:
5 divided by 81 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 81

Let's proceed to step 2:
81 goes into 58 0 times with a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Include the next digit (9) from the dividend after 58, then repeat: 589 / 81

On to step 3:
The number 81 fits into 589 7 times, leaving a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 567 from 589 leaves us with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 81

Moving on to step 4:
81 can be fit into 220 2 times, resulting in a remainder of 58.
The next digit of our result is 2. 
Result so far: 72.0
If we take 162 away from 220, we end up with 58.
Grab the next digit (0) from the dividend, add it to 58, then carry on: 580 / 81

Moving on to step 5:
If we divide 580 by 81, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 727.0
Deduct 567 from 580 and we're left with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 81

Moving on to step 6:
81 goes into 135 1 times with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 7271.0
If we take 81 away from 135, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
When dividing 540 by 81, we get 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 7271.6
Deduct 486 from 540 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
81 can be fit into 540 6 times, resulting in a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 7271.66
Deduct 486 from 540 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 7271.66 with a remaining 0.054.
