47187 divided by 81 
The aim is to understand the frequency of 81 in 47187.

Advancing to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 81

Let's proceed to step 2:
If we divide 47 by 81, we get 0 and a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Append the next digit (1) from the dividend to 47 and continue with: 471 / 81

Step 3:
When dividing 471 by 81, we get 5 with a remainder of 66.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 405 from 471, we get 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 81

Going ahead to step 4:
668 divided by 81 is 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we subtract 648 from 668, we get 20.
Append the next digit (7) from the dividend to 20 and continue with: 207 / 81

Advancing to step 5:
81 goes into 207 2 times with a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 582.0
Deduct 162 from 207 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 6:
81 goes into 450 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 582.5
If we take 405 away from 450, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
81 can be fit into 450 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 582.55
Subtract 405 from 450 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 582.55 with a remainder of 0.045.
