We're dividing 470049 by 81 
The aim is to understand the frequency of 81 in 470049.

Advancing to step 1:
81 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 81

Advancing to step 2:
81 can be fit into 47 0 times, resulting in 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.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 81

Going ahead to step 3:
When dividing 470 by 81, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 65 after subtracting 405 from 470.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 81

Moving on to step 4:
81 goes into 650 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtract 648 from 650 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 81

Moving on to step 5:
24 divided by 81 is 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 580.0
The remainder is 24 after subtracting 0 from 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 81

Step 6:
The number 81 fits into 249 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 5803.0
Deduct 243 from 249 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 81, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5803.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 81, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 5803.07
Deduct 567 from 600 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
If we divide 330 by 81, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 5803.074
Deduct 324 from 330 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
81 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 5803.074
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
81 can be fit into 600 7 times, resulting in a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 5803.07407
If we take 567 away from 600, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
81 goes into 330 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 5803.074074
If we take 324 away from 330, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
60 divided by 81 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 5803.074074
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
The number 81 fits into 600 7 times, leaving a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 5803.07407407
The remainder is 33 after subtracting 567 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The quotient of the division is 5803.07407407, and the remainder is 3.3e-08.
