47147897 divided by 81 
The aim is to understand the frequency of 81 in 47147897.

On to step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 81

On to step 2:
When dividing 47 by 81, we get 0 with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 81

Step 3:
81 can be fit into 471 5 times, resulting in a remainder of 66.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 66 after subtracting 405 from 471.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 81

Step 4:
If we divide 664 by 81, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtracting 648 from 664 leaves us with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 81

On to step 5:
The number 81 fits into 167 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 582.0
If we subtract 162 from 167, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 81

Going ahead to step 6:
When dividing 58 by 81, we get 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 5820.0
The remainder is 58 after subtracting 0 from 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 81

Let's proceed to step 7:
81 can be fit into 589 7 times, resulting in a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 58207.0
Subtract 567 from 589 to get 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 81

Moving on to step 8:
When dividing 227 by 81, we get 2 with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 582072.0
The remainder is 65 after subtracting 162 from 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
The number 81 fits into 650 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 582072.8
Subtracting 648 from 650 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
When dividing 20 by 81, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 582072.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
If we divide 200 by 81, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 582072.802
Deduct 162 from 200 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
If we divide 380 by 81, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 582072.8024
Subtracting 324 from 380 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
81 goes into 560 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 582072.80246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
When dividing 740 by 81, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 582072.802469
If we subtract 729 from 740, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 15:
When dividing 110 by 81, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 582072.8024691
Subtract 81 from 110 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 16:
290 divided by 81 is 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 582072.80246913
If we subtract 243 from 290, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

In conclusion, the division gives 582072.80246913 with a balance of 4.7e-08.
