470769 divided by 81 
The aim is to understand the frequency of 81 in 470769.

On to step 1:
When dividing 4 by 81, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 81

Step 2:
47 divided by 81 is 0 with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 81

Step 3:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 405 away from 470, we end up with 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 81

Going ahead to step 4:
If we divide 657 by 81, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtract 648 from 657 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 81

Step 5:
81 can be fit into 96 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 581.0
Subtracting 81 from 96 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 81

On to step 6:
159 divided by 81 is 1 with a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 5811.0
If we take 81 away from 159, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
If we divide 780 by 81, we get 9 and a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 5811.9
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 8:
81 goes into 510 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 5811.96
Subtracting 486 from 510 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
When dividing 240 by 81, we get 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 5811.962
Subtracting 162 from 240 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
If we divide 780 by 81, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 5811.9629
If we subtract 729 from 780, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 11:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 5811.96296
Deduct 486 from 510 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
81 can be fit into 240 2 times, resulting in a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 5811.962962
Subtracting 162 from 240 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 13:
If we divide 780 by 81, we get 9 and a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 5811.9629629
Subtract 729 from 780 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 14:
81 can be fit into 510 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 5811.96296296
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 5811.96296296 with a balance of 2.4e-08.
